Answer:
90
Step-by-step explanation:
supplementary angles equal 180 degrees and 90+90=180
Answer:
90°
Step-by-step explanation:
Supplementary angles are angles that add up to 180°.
Congruent means the angles are equal to each other.
Since there are two angles, and they have to be equal to each other, we can divide 180° by 2 to find the measure of each angle.
180° / 2 = 90°
Both angles have a measure of 90°.
