In parallelogram WXYZ, CY is 15ft.
What is Parallelogram?
A parallelogram defined as a special type of quadrilateral which has both pairs of opposite sides parallel and equal.
In a parallelogram the diagonals bisects each other.
WC= CY
x+4 = 2x -7
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 determine CY
CY = 2x-7
Substitue x =11
CY = 2(11) - 7 = 22-7
CY = 15
