Question

Find the value of x.

Answer 1

Answer:

x = 5.

Step-by-step explanation:

ZY = 2*2x = 4x.   (Parallel line in a triangle theorem).

XZ = 2 * (4x + 1) = 8x + 2

XY = 2 *(2x + 3) = 4x + 6

So the perimeter 88 = 4x + 8x + 2 + 4x + 6

88 - 8 = 16x

16x = 80

x = 5.

(Sorry but I can't remember the exact name of the theorem).
