Question

Solve for x in the following parallelogram. Show your work for full credit.

Answer 1

Answer: 8

Work Shown:

S+R = 180

(4+9x) + (104) = 180

9x+108 = 180

9x = 180-108

9x = 72

x = 72/9

x = 8

Note: Adjacent angles of any parallelogram are supplementary, meaning they add to 180 degrees.
