Work Shown:
If we want this figure to be a parallelogram, then the opposite sides EH and FG must be the same length.
Let's use that fact to solve for x.
EH = FG
17x-29 = 12x-8
17x-12x = -8+29
5x = 21
x = 21/5
x = 4.2; answer is choice A
Extra info:
If x = 4.2, then,
EH = 17x-29 = 17*4.2-29 = 42.4FG = 12x-8 = 12*4.2-8 = 42.4Both EH and FG are 42.4 units long which helps confirm the answer.
