Answer:
11.2 inches.
Step-by-step explanation:
Applying the tangent/secant theorem:
9^2 = 5(y + 5)
5y + 25 = 81
5y = 56
y = 11.2 in.
To solve for x you do these steps
x=number
1. do this following multiplication problem to get 0.9%
36/x*100%= 0.9%
2. now do the opposite of what you did before to get x
36 divided by 0.9%= x
36 divided by 0.9%= 40
x = 40
I think the answer is C but i’m not completely sure
calm down and try to complete the questions
One width and one length is half the perimeter.
90/2 = 45
Let the width = X
the length is 2 times the width so 2X
The sum of the two equals 45"
2X + X = 45
Simplify:
3x = 45
Divide both sides by 3:
x = 15
The width is 15 inches
Length = 30 inches.
Area = Length x width = 15 x 30 = 450 in^2
The area 450 in^2
