Question

Solve for x…………………….

Answer 1

x = 15

Explanation:

the figure has one pair of parallel sides and is therefore a trapezoid.

the lower base angle is supplementary to the upper base angle on the same side, then

8x + 6 + 54 = 180

8x + 60 = 180 ( subtract 60 from both sides )

8x = 120 ( divide both sides by 8 )

x = 15
