Question

I need assistance with this question. The degree's I have listed below are the choices I have from the drop-down menu. Anyone know which one should be paired with which measure?

m∠x = 45°, 56°, 63°, 72°

m∠y = 45°, 56°, 63°, 72°

m∠z = 45°, 56°, 63°, 72°

(Picture also included.)

Answer 1

angle B& C = 180

C & D = 180

A & D = 180

A & B = 180

A & C are identical so angle x = 63

angle Z = mirrored angle which is 72

180-63 = 117-72 = 45

so angle y = 45
