2. Which of the following angles are supplementary to Z2? Select all
that apply.
A 25 B 26 CZ7 D 28

Question is not clear, I believe some information is missing or you mistyped something..

Anyways supplementary angles are angles that add up to 180.

So you just need to choose the angle that if you add it to z2 (not sure what that is) it will give you a sum of 180.

On the other hand complimentary angles add up to 90.
