Question

Given parallelogram BCDE

what is the equation to find x?
what is x?
what is length of side CD?

please help​

Answer 1

x=3

CD = 13

Explanation:

BE = CD in a parallelogram

1+4x = 5x -2

Subtract 4x from each side

1+4x-4x = 5x-2 -4x

1 = x-2

Add 2 to each side

1+2 = x-2+2

3 =x

The length of CD

CD = 5x-2 = 5*3 -2 = 15-2 = 13
