90+ POINTS PLEASE HELP Choose one problem below and use trigonometry to solve for a missing angle x of the right triangle
Answers
Answer:
[tex]x\approx49.3266\textdegree[/tex]
Step-by-step explanation:
So we want to find Angle x.
Note that we already know the side length of the side opposite to Angle x.
We also know that the hypotenuse is 56.3.
Therefore, we can use the sine function. Recall that:
[tex]\sin(x)=\frac{\text{opposite}}{\text{hypotenuse}}[/tex]
The opposite side is 42.7. The hypotenuse is 56.3. Substitute:
[tex]\sin(x)=\frac{42.7}{56.3}[/tex]
Take the inverse sine of both sides.
[tex]\sin^{-1}(\sin(x))=\sin^{-1}(\frac{42.7}{56.3})[/tex]
The left side cancels:
[tex]x=\sin^{-1}(\frac{42.7}{56.3})[/tex]
Use a calculator. Thus:
[tex]x\approx49.3266\textdegree[/tex]
And that's our answer :)
Answer:
[tex]\Huge \boxed{\mathrm{49.33 \° }}[/tex]
[tex]\rule[225]{225}{2}[/tex]
Step-by-step explanation:
The triangle is a right triangle.
We can use trig functions to solve for the missing angle.
[tex]\displaystyle \mathrm{sin \theta =\frac{opposite}{hypotenuse} }[/tex]
The opposite side to angle x is 42.7.
The hypotenuse of the right triangle is 56.3.
[tex]\displaystyle \mathrm{sin} (x)=\frac{42.7}{56.3}[/tex]
Taking inverse sin of both sides.
[tex]\displaystyle x=\mathrm{sin^{-1}}( \frac{42.7}{56.3})[/tex]
[tex]x= 49.3265955[/tex]
The missing angle measures approximately 49.33°.

Step-by-step explanation:
Remember: the midsegment is always parallel to the third side, and the length is half of the third side. (Third side = XY) Assuming that line segment XY is the length of the third side of the triangle, we can insert it into this equation:
[tex]m=\frac{AB}{2}[/tex]
Let's plug in XY for AB.
[tex]m = \frac{XY}{2}[/tex]
[tex]m=\frac{12}{2} \\[/tex]
[tex]AC=6[/tex]
Our final answer: AC = 6

x>5
A number is larger than 5.
x 25
A number is below 5.
X35
A number is not less than 5.
*<5
A number is at most 5.
Answers
Answer/Step-by-step explanation:
The following inequalities can be translated and matched as follows:
1. A number is larger than 5:
Let that number be x. Numbers that are larger than 5 are 6, 7, 8 and so on. Therefore, the number that is larger is greater than 5. This can be represented in the symbolic form as:
x > 5
2. A number is below 5:
Numbers that are below 5 are 4, 3, 2 and so on. Therefore, we can say the number, x, is less than 5. This can be written in symbolic form as:
x < 5
3. A number is not less than 5:
A number that is not less than 5 could equal 5 or any other number that is larger than 5. Therefore, we can say the number, x, equals 5 or greater than 5. This can be written as:
x ≥ 5
4. A number is at most 5:
At most 5, means the number, x, is either 5 or less than 5. This can be written as:
x ≤ 5

Answers
Answer:
The correct option is Segment Addition Postulate
Step-by-step explanation:
The segment addition postulate states that where there are two points on a line A and C and a third point B can only be located on the line segment AB if and only if the the distances between point A and point B as well as the distance between point B and point C satisfy the equation AB + BC = AC
Therefore, given that in the figure, the point B is in between point A and point C on segment AC then AB + BC
Similarly, AD = AE + ED.

find the length of the missing side of the right triangle.
Answers
5^2 (five squared) plus 12^2 (twelve squared) and add them using the equation a^2+b^2= c^2. Now you square 5 and 12 to get 25 and 144. You add them together and get 169. Take the square root of 169 and c. The square root on c will cancel out the squared (to the power of two) part leaving you with just c. And the square root of 169 is 13. So c (the missing length) is 13. C=13.
Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{13 \: \: units \: }}}}}[/tex]
Step-by-step explanation:
Perpendicular ( p ) = 5
Base ( b ) = 12
Hypotenuse ( h ) = ?
Finding the length of missing side
Using Pythagoras theorem
[tex] \boxed{ \sf{ {h}^{2} = { p}^{2} + {b}^{2} }}[/tex]
plug the values
⇒[tex] \sf{ {h}^{2} = {5}^{2} + {12}^{2} }[/tex]
Evaluate the power
⇒[tex] \sf{ {h}^{2} = 25 + 144}[/tex]
Add the numbers : 25 and 144
⇒[tex] \sf{ {h}^{2} = 169}[/tex]
Squaring on both sides
⇒[tex] \sf{ \sqrt{ {h}^{2} } = \sqrt{169}} [/tex]
Calculate
⇒[tex] \sf{ {h} = 13 \: units}[/tex]

How is the intersection point of two linear functions related to solving
a linear equation?
Answers
Answer:
Linear equation formed by equating both functions is used to find the x-coordinate of the intersection point.
Step-by-step explanation:
If we have two linear functions f(x) and g(x) which are intersecting at a point (a,b), then equating both functions we get a linear equation as
[tex]f(x)=g(x)=y[/tex]
On solving this linear equation we get the x-coordinate of the point of intersection, i.e., x=a.
After that, we need to substitute x=a in either f(x) or g(x) to get the y-coordinate of the point of intersection.
Therefore, the linear equation formed by equating both functions is used to find the x-coordinate of the intersection point.

Once you plug in the numbers, you can solve each equation separately. You’ll see that g(9) is equal to 757 and f(4) is equal to 51.
Now since the question is asking for g(9)+f(4) you can now do 757+51 which is equal to 808.
I hope I got all the numbers right, but if I didn’t you get the point.
A Farmer picks 242 apples on Monday and 118 apples on Tuesday. On Wednesday, she sells 109 of the apples at the market. Which equation can be used to find a, the number of apples of farmer has left?
Answers
Answer:
the farmer has 242 apples left
Step-by-step explanation:
A = awnser
M= Monday
T= Tuesday
M= 242
T= 109
W = amount sold or 109
(M+T)-W= total amount left
use order of operations and add whats in the ( )
( 242+109 ) = 351 or ( M+T )
then you would use the sum of ( M+T ) and subtract W or 109 wich would then equal 242 so the equation
( 242+109 ) - 109 would equal 242 or ( M+T ) - W = A

You earn $28 for washing 7 cars. How much do you earn for washing 6 cars?
Answers
━━━━━━━━━━━━━━━ ♡ ━━━━━━━━━━━━━━━
Since you can earn 28 dollars by washing 7 cars, and you want to find the amount money you can make by washing 6 cars.
[tex]\frac{28}{7} = \frac{x}{6}[/tex]
First, you should find the amount of money you can make by washing 1 car (unit rate).
[tex]\frac{28}{7} = \frac{x}{1}[/tex]
To get from 7 to 1, you have to divide 7 by 7; 7 ÷ 7 = 1.
Do the same thing to the numerator; 28 ÷ 7 = 4.
Now you know how much you make by washing 1 car, you need to find how much you make by washing 6 cars.
[tex]\frac{4}{1} = \frac{x}{6}[/tex]
To get from 1 to 6, you multiply by 6. 1 times 6 equals 6.
Now do the same thing to the numerator; 4 × 6 = 24.
You can earn 24 dollars by washing 6 cars.

are the expressions 2(3x - 6) and 2(3x)x - 6 are equivalent
Answers
Answer:
No
Step-by-step explanation:
So lets do the first expression first
2(3x-6)
6x-6
So the first one is 6x-6
Now the second expression
2(3x)x-6
As you can see here, there's an extra x in this problem compared to the last problem, but lets still work it out
6x*x-6
So they are different.
If the extra x wasn't there then it would've worked.

What is equation?Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign. It shows the relationship of equality between the expression written on the left side with the expression written on the right side. In every equation in math, we have, L.H.S = R.H.S.
There are different parts of an equation which include coefficients, variables, operators, constants, terms, expressions, and an equal to sign. When we write an equation, it is mandatory to have an "=" sign, and terms on both sides. Both sides should be equal to each other. An equation doesn't need to have multiple terms on either of the sides, having variables, and operators. An equation can be formed without these as well, for example, 5 + 10 = 15.
