Question

In parallelogram WXYZ, what is CY?
11 ft
15 ft
21 ft
23 ft

Answer 1

B aka 15 ft

Explanation:

just did it on edg :)

Answer 2

15 ft

Explanation:

In a parallelogram the diagonals bisects each other

So WC= CY

`x+4=2x-7` solve the equation for x

Subtract x from both sides

`x-x+4=2x-x-7`

`4=x-7`

Now we add 7 on both sides

`4+7=x-7+7`

x=11

Now we need to find CY

`CY= 2x-7`

Plug in 11 for x

`CY= 2(11)-7=22-7= 15`
