Question

In parallelogram WXYZ, what is CY?

CY =
ft

Answer 1

CY = 15 ft (option B)

Answer 2

the complete question in the attached figure

we know that
C is the midpoint of parallelogram WXYZ
so
WC=CY
WC=x+4
CY=2x-7

then
x+4=2x-7----------------> 2x-x=4+7-------------> x=11

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

the answer is
CY=15 ft
