Question

< A and < B are complementary and congruent. What is the measure of each of these angles?

90°
45°
50°
180°

Answer 1

complementary , sum of both angles = 90
congruent <A = <B

so answer 45° 

Answer 2

Answer:

< A = < B = 45°

Step-by-step explanation:

First, you have to  both concepts: congruent and complementary.

We say two angles are complementary when together they made a 90° angle.

We say two angles are congruent when both have the same amplitude.

For two angles to be complementarity and congruent both have to be the same and together be 90°

So 90°/2=45°

Both angles are 45°
