Question

Parallelogram W X Y Z is shown. Diagonals are drawn from point W to point Y and from point Z to point X and intersect at point C. The length of W C is (x + 4) feet and the length of C Y is (2 x minus 7) feet.

In parallelogram WXYZ, what is CY?

Answer 1

15

Explanation:

Answer 2

CY = 15

Explanation:

In parallelogram, diagonals bisect each other.

Therefore, CY = WC

2x - 7 = x + 4

2x - x = 4 + 7

x = 11

CY = 2x - 7 = 2*11 - 7 = 22- 7 = 15
