Laney · Answer 1

This is what the parallelogram will look like, and since BC and AD should equal the same length, you set them equal to each other to find x.

3x+15 = 5x+3

12 = 2x

6 = x

Now that you have found x you plug it in to the equation of length AD.

5 (6) + 3 = 30+3 = 33

Your answer should be 33.
