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
