Answer:
Step-by-step explanation:
You have 2 sides given in a right triangle. You can make an equation that will solve for x. In fact the tangent will do. There's no need to solve for the third side.
Tan(x) = opposite / adjacent
opposite = 39
adjacent = 76
Tan(x) = 39/76
Tan(x) = 0.5132
When finding an angle, you need to use the inverse tan.
x = tan-1(0.5132) Use 2nd function tan(x)
x = 27.16 degrees.
Step-by-step explanation:
first we need the length of the Hypotenuse (UW).
Pythagoras :
c² = a² + b²
with c being the Hypotenuse (the side opposite of the 90 degree angle).
UW² = 76² + 39² = 5,776 + 1,521 = 7,297
UW = sqrt(7297) = 85.42247948...
now we get x from the law of sine :
sinA/a = sinB/b = sinC/c
with the angles always being opposite of the sides.
so, we have
sin(x)/39 = sin(90)/sqrt(7297) = 1/sqrt(7297)
sin(x) = 39/sqrt(7297) = 0.456554296...
x = 27.16498506...° ≈ 27.2°
we could have done it without the Hypotenuse first.
as the angle W is 90-x
sin(x)/39 = sin(90-x)/76 = cos(x)/76
sin(x)/cos(x) = 39/76 = tan(x) = 0.513157895...
x = 27.16498506...° ≈ 27.2°
as expected, it is precisely the same result.

A couple can afford to make a monthly mortgage payment of $700. If the mortgage rate is 2% and the couple intends to secure a 30-year mortgage, how much can they borrow?
========================================================
Explanation:
r = 0.02 = decimal form of 2% annual interesti = monthly interest ratei = r/12 = 0.02/12 = (2/100)/12 = 1/600.n = number of months = 12*30 = 360P = monthly payment = 700We'll plug those items into the formula below.
L = loan amount
L = P*( (1+i)^n - 1)/( i*(1+i)^n )
L = 700*( (1+1/600)^360 - 1 )/( 1/600*(1+1/600)^360 )
L = 189,383.961539639
L = 189,383.96
The couple can afford to borrow at most $189,383.96
A police car leaves a crime scene heading east directly towards the hospital at 72 kilometres per hour. An ambulance leaves a quarter of an hour later and also heads directly east towards the hospital at 81 kilometres per hour. How long will it take for the ambulance to pass the police car?
It will take 2 hours for the ambulance to pass the police car.
Given that a police car leaves a crime scene heading east directly towards the hospital at 72 kilometers per hour, and an ambulance leaves a quarter of an hour later and also heads directly east towards the hospital at 81 kilometers per hour, to determine how long will it take for the ambulance to pass the police car, the following calculation must be performed:
72 x 0.25 = 18 81 - 72 = 9 18/9 = 2 72 x 0.25 + 72 x 2 = 162 81 x 2 = 162
Therefore, it will take 2 hours for the ambulance to pass the police car.

Step-by-step explanation:
The PTA was doing a fundraiser and bought 500 megaphones to sell for a pep rally. The profit, p, from the sale of megaphones can be represented by p(m) = 3.5m-875. Which inequalities represents the constraints of the range?
A. m>= - 875
B. 0<=p(m) <- 500
C. 0<=m<=500
D. p(m) >= -875
The inequality which represents the constraints of the range is D. p(m) ≥ -875
Since the PTA was doing fundraiser and bought 500 megaphones to sell for the pep rally, and the profit, p, from the sale of megaphones can be represented by p(m) = 3.5m - 875 where m = number of megaphones sold.
To find the inequalities represents the constraints of the range of p(m), we need to know the domain of m.
Since we have 500 megaphones and we can sell from 0 to 500 inclusive. So, the domain of m is 0 ≤ m ≤ 500.
To determine the range of p(m), we insert the values of m at its extreme points into p(m).
So, when m = 0
p(m) = 3.5m - 875
p(0) = 3.5(0) - 875
p(0) = 0 - 875
p(0) = -875
when m = 500
p(m) = 3.5m - 875
p(500) = 3.5(500) - 875
p(500) = 1750 - 875
p(500) = 875
Since for a profit, m ≥ 0. So, p(m) ≥ p(0) = -875
So, p(m) ≥ -875
So, the inequality which represents the constraints of the range is D. p(m) ≥ -875

How to Overcome Insecurity
Step 1
The first step of Voice Therapy involves vocalizing your self-critical thoughts in the second person.You can also write down these thoughts.
Step 2
In the second step, you can start to think and talk about the insights and reactions you have to exposing these mean thoughts.
Step 3
People often struggle with the third step of this process, because it involves standing up to long-held beliefs and insecurities about oneself. You will answer back to your voice attacks, expressing your real point of view.
Step 4
In step five of Voice Therapy, you start to make a connection between how the voice attacks are influencing your present-day behaviors.
Step 5
The final step involves making a plan to change these behaviors. If insecurity is keeping you from asking someone on a date or going after a promotion, it’s time to do the actions anyway. If you’re indulging in self-hating thoughts that encourage you to engage in self-destructive behaviors, it’s time to interrupt these behaviors and unleash the real you.

Answer:
Step-by-step explanation:
It looks like you need to solve this system of equations.
That means we need to find a value for x and a value for y that makes both equations true.
Since both equations have a 3y in them, this system is ready to use a method called "elimination method"
Since the x terms are lined up, and the y terms are lined up, the equal signs are lined up, and the constants are lined up...you can subtract the bottom equation from the top equation.
5x + 3y = 41
2x + 3y = 20
Subtract and you will get
3x + 0y =21
We don't need to write that 0y, because it is 0.
3x = 21, now divide by 3
x = 7, almost finished!
Use x = 7 in either of the original equations to find y.
5x + 3y = 41 and x = 7
5•7+ 3y = 41
35 + 3y = 41
-35 -35
3y =6
y = 2
So the solution is x=7 and y=2
That can also be written as an ordered pair (7, 2)

An English teacher has equal numbers of fiction, literature,
and poetry books. Each day, she randomly selects one book
to read from. She designs a simulation to estimate the
probability that the next three books she selects are all
literature.
Which simulation design could she use to estimate the
probability?
The simulation design could she use to estimate the probability is
Number cube
Let 1, 6 = literature
Let 2, 5 = fiction
Let 3, 4 = poetry
Roll the cube three times. Repeat.
What is simulation?Simulation is the process of creating a model or representation of a real-world system or process and conducting experiments with the model to observe how it behaves or performs under different conditions.
We have,
This simulation design assigns each book in the teacher's collection a unique number from 1 to 6, with literature books assigned the numbers 1 and 6, fiction books assigned the numbers 2 and 5, and poetry books assigned the numbers 3 and 4.
Rolling a number cube simulates the teacher randomly selecting a book each day, and repeating this process three times allows for the estimation of the probability that three consecutive selections will be literature books.
This simulation design is appropriate because it accurately represents the probabilities of selecting literature, fiction, and poetry books from the teacher's collection and allows for repetition to simulate multiple days of book selections.
Thus,
The simulation design could she use to estimate the probability is

Trey bought a football on sale for 15% off of $45. Evan bought the same football at a different store for 25% off of $54. Who received the better deal? Explain.
a. How much did Trey spend on a football?
b. How much did Evan spend on a football?
c.
Who got the better deal?
Answer:
a. $38.25, b.$40.5, c. Trey
Step-by-step explanation:
A percentage can also be represented as a proportion out of 1; for example, 30 percent is .30, and 100 percent will be 1.00.
a. If Trey is paying 15 percent off a price, that means he is still paying 85 percent, and recall what I said earlier, about 85 percent is a .85 proportion. So now we multiply the price by the proportion he is paying .85*45 = $38.25
b. We want to do the same process we did in part a. So we have 1 - .25 =.75 to get the proportion of the original price Evan will be paying. Now we multiply .75*54 = $40.50.
c. Trey got the better deal because he ended up paying less; hence $38.25 is less than that of $40.50
How to determine if Triangles are Congruent?
If they are, how do you know if they are SSS or ASA or SAS or AAS?
Essentially, how do I apply the different congruent thermos to the questions attached?
So basically what you have to do is first identify all of the sides or angles that equal eachother then you can see if you did a side side and side in a row etc, like 44 would be SAS because the vertical angles would be inbetween the two sides. 46 would be SSS because after you make the line in the middle for reflexive property you can see that there are three sides in a row.

Pieter wrote and solved an equation that models the number of hours it takes to dig a well to a level of 72 feet below sea level.
7h – 5(3h – 8) = –72
Which statement is true about Pieter’s solution?
1. It cannot be a fraction or decimal because the depth of the well is a whole number.
2. It must be a positive number since it represents a number of hours.
3. It must be a negative number because the depth is below sea level.
4.It cannot be greater than –72 because that is the depth of the well.
Answer:
Step-by-step explanation:
Is this the entire question? Some of it makes no sense without a diagram or something.
To get rid of A you actually have to solve the equation.
7h – 5(3h – 8) = –72 Remove the brackets
7h - 15h + 40 = - 72 Combine the like terms
- 8h + 40 = - 72 Subtract 40 from both sides
- 8h = -112 Divide by -8
h = 14
Well the depth is a whole number so A is true.
We don't know anything about time. But the answer is positive.
C is false because B is true.
We don't know exactly what the depth of the well is.
I would pick A, but you need the entire question.
