Answer:
15 ft
Step-by-step explanation:
In a parallelogram the diagonals bisects each other
So WC= CY
[tex]x+4=2x-7[/tex] solve the equation for x
Subtract x from both sides
[tex]x-x+4=2x-x-7[/tex]
[tex]4=x-7[/tex]
Now we add 7 on both sides
[tex]4+7=x-7+7[/tex]
x=11
Now we need to find CY
[tex]CY= 2x-7[/tex]
Plug in 11 for x
[tex]CY= 2(11)-7=22-7= 15[/tex]
