I need help with my math
Answers
Answer:
16
Step-by-step explanation:
The formula for finding the length of a side of a right triangle is:
A^2 + B^2 = C^2 (c being the hypotenuse.)
We know what the length of the hypotenuse and one of the legs is, so we can solve by taking B^2 (the leg measuring 12) and subtracting it from C^2 (the hypotenuse) and then finding the square root of C^2.
20^2 - 12^2 = 256
or in simpler terms
20^2 - 144 = 256
Then, if we find the square root of 256 we get 16. We can check our work by substituting it back into the equation
16^2 + 12^2 = 20^2
or in simpler terms
256 + 144 = 400
So the length of the missing leg is 16. I hope this helps :)
Answer:
C. 16
Step-by-step explanation:
In order to find one side of a right triangle, given two sides, you can use the Pythagorean theorem: [tex]A^2+B^2=C^2[/tex]
We already have the values of one of the bases (12) and the hypotenuse (20), so we are looking for the second base. So, we have the values of B and C, and we need to find A.
To find A, put the values you already have into the formula as follows:
[tex]A^2+12^2=20^2[/tex]
Next, square each value:
[tex]A^2+144=400[/tex]
Subtract 144 from 400 to simplify the equation.
[tex]A^2=256[/tex]
And finally, find the square root of 256 to find A.
[tex]A=16[/tex]
Final answer:
C. 16

If the diagonals of a quadrilateral are congruent, is the quadrilateral always a rectangle?
Answers
Answer:
Yes
Step-by-step explanation:
The only quadrilaterals with congruent diagonals are squares and rectangles and squares are technically rectangles so the answer is yes.
If the diagonals of a quadrilateral are congruent. Then the quadrilateral is always a rectangle which is false.
What is a quadrilateral?The quadrilateral has four sides and four angles. The sum of internal angles is 360 degrees.
It is a polygon with four sides. The total interior angle is 360 degrees. A rectangle's opposite sides are parallel and equal, and each angle is 90 degrees. Its diagonals are all the same length and intersect in the center.
If the diagonals of a quadrilateral are congruent. Then the quadrilateral can be a square or a rectangle.
If the diagonals of a quadrilateral are congruent. Then the quadrilateral is always a rectangle which is false.

Answer:
Step-by-step explanation:
Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
we can find angle C b/c the angles of a triangle always add to 180 , soo
180= C + 81 +63.5
35.5 = C
now that we have angle C and we know the Hyp we can use sin to find side g
where g = Opp and Hpy = 13.8 for this question
Sin(35.5) = Opp / 13.8
13.8*Sin(35.5) = Opp
8.0137 = Opp
g = 8.0137
next they ask for the area of the biggest triangle ABC ( there are two smaller ones when you use D )
we can use 1/2 * base * height , but we don't know the base yet, even thou we do know the height.
we can solve for line segment CD and DB and then add them for the side a .. or the base of the biggest triangle sooo.. CD = adj
Cos(35.5) = Adj / 13.8
13.8*Cos(35.5) = Adj
11.234794 =Adj
now solve for DB using cos again but with the other smaller triangle where Adj = DB now
Cos(63.5) = Adj / 8.9
8.9*Cos(63.5) = Adj
3.971160
add these two Adjs together to get the total 'a' side
15.205954
now plug in side a as the base and g as the height of our biggest triangle
Area = 1/2 * 15.205954 * 8.0137
Area = 60.9159
rounded to 2 sig figs
Area = 60.92 :) hope you get an "A" :P

The expression 16t² represents the distance, in feet, an object falls after t seconds. The object is dropped from a height of 906 feet.
Answers
Complete Question:
The expression 16t² represents the distance in feet an object falls after t seconds. The object is dropped from a height of 906 feet. What is the height in feet of the object 2 seconds after it is dropped?
Answer:
H(2) = 842 feet
Step-by-step explanation:
Let the height be H.
Given the following data;
H(t) = 16t²
Height, H = 906 feet
Time, t = 2 seconds
To find the time, t at 2 seconds, we would use the following formula;
H(t) = H - 16t²
H(2) = 906 - 16(2)²
H(2) = 906 - 16*4
H(2) = 906 - 64
H(2) = 842 feet
Therefore, the height in feet of the object 2 seconds after it is dropped is 842.

Answers
Answer:
1/7
Step-by-step explanation:
Given that :
Line AB contains points A (8, −4) and B (1, −5)
Slope = Rise / Run
Rise = y2 - y1 = - 5 - (-4) = - 5 + 4 = - 1
Run = x2 - x1 = 1 - 8 = - 7
Slope = Rise / Run = - 1 / - 7
Slope = 1/7
