Answer:
The answer is C: 68
Explanation:
The trapezoid has a total amount of 360 degrees.
W = 112 degrees.
W and X are congruent so X also equals 112
SO if you add them together, it is equal to 224.
Subtract from 360 and 136 is left.
Divide by 2 because there is Z and Y(2 angles left) which are also congruent.
This gives the angles measurements of 68 for both Z and Y
