Question

AE,BF,CG,DH are all parallel to each other. Also EF=FG=GH

If AB=5x and CD = 2x +12, then find x and find BC.

See photo for figure.

Answer 1

Answer:

x = 4

BC = 20

Step-by-step explanation:

From what we have, the measures EF = FG = GH

That means;

AB = CD

Thus;

5x = 2x + 12

5x - 2x = 12

3x = 12

x = 12/3

x = 4

BC = AB = CD = 5(4) = 2(4) + 12 = 20
