What is the sum of supplementary angles?

45 degrees
90 degrees
180 degrees
360 degrees

The correct answer is: 180 degrees

Supplementary angles are two angles that add up to 180 degrees. This is a fundamental property of angles, where if you have two angles and their measures sum up to 180 degrees, they are known as supplementary angles. In this case, the correct answer is C, which is 180 degrees. Option A, 45 degrees, is not the sum of supplementary angles. Option B, 90 degrees, is the measure of a right angle and not the sum of supplementary angles. Option D, 360 degrees, is the measure of a full circle and is not the sum of supplementary angles.
