Question

1. Solve for x in the following problem. You MUST show the equation you set up to solve and the associated work to get to the final answer.

Answer 1

x = 5

Explanation:

if the lines are parallel, the triangles are similar and thus proportional

set up a proportion:

22/8 = (6x+3)/12

8(6x+3) = (22)(12)

48x + 24 = 264

48x = 240

x = 5
