D would be the correct answer. Since angle W and angle Z form a straight line, they are supplementary angles. Supplementary angle add up to make 180°, which is what D states.
A doesn't make sense.
If B was true, then the angles would be complementary (adding up to 90°). They form a straight line, though, so it's incorrect.
C is wrong for reasons aforementioned.
