Answer 1

Answer:

B aka 15 ft

Step-by-step explanation:

just did it on edg :)

Answer 2

Answer:

15 ft

Step-by-step 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

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