The key fact here is that all the perpendiculars meet at one point and they are all equal. So pick any two givens and equate them.

Equation

3x + 7 = 5x - 11               Add 11 to both sides.

Solution

3x + 7 +11 = 5x - 11 + 11   Combine like terms on both sides. - 11 + ll = 0

3x + 18 = 5x                    Subtract 3x from both sides.

3x - 3x + 18 = 5x - 3x      Combine

18 = 2x                             Divide by 2

2x/2 = 18/2

x = 9

They want AI

AI = 3x + 7

x = 9

AI = 3*9 + 7

AI = 27 + 7

AI = 34

Find the value of CI

CI = 52 - 2x

CI = 52 - 2*9

CI = 52  - 18

CI = 34
