Answer:
B. 24 in
Step-by-step explanation:
Add the known sides = 19 in
To solve for the two unknown sides -
Side across from the vertical 3 in is the same, so add another 3 inches to 19 = 22 in
For the side across from the 7in you need to subtract the horizontal sides next to it that you already know.
7 = 3 + 2 +x
x = 2
so add 2 in
22 + 2 = 24in

Answer: Q1.=145, Q2.=20
Step-by-step explanation:
two supplementary angles equal 180
1. 180-35=145
2 . complementary angles , both add up to 90
90-70=20
Answer:
We will add 3 to each side of the equation
Step-by-step explanation:
x^2 − 8x + 13 = 0
We want to complete the square
We will subtract 13 from each side of the equation
x^2 -8x +13 -13 = 0 -13
x^2 -8x = -13
Then take the coefficient of x
-8
Divide by 2
-8/2 = -4
Square it
(-4)^2 = 16
Add this to each side
x^2 -8x +16 = -13+16
( x-4) ^2 = 3
The sum of subtracting 13 and adding 16 is adding 3
