Ответ:
I think the answer for Z is actually 40 degrees.
Step-by-step explanation:
We can use y to find the lower left angle of the triangle Z is a part of. Since Y is 78 degrees, the other side would be 78 degrees as well. Since the lower base angles are congruent between C and D and n is 62 degrees, we can find the answer. So, 78 + 62 = 140, which is 40 away from 180. The answer is 40.
