Question

If two angles are both vertical and supplementary, can we determine the angles? If so, what are they?

Answer 1

Explanation:

45

Answer 2

we know that
if A and B are vertical angles
so
angle A is equal angle B
A=B

and
if A and B are supplementary angles
so
angle A +angle B is equal to 180 degrees
A+B=180°

therefore
A=B
A+A=180-----> 2A=180-----> A=90°

the answer is
the angles are 90 degrees
