Answer:
Explanation:
Two angles are said to be supplementary if their sum is equal to 180 degrees. In other words, if two angles add up to 180 degrees, they are supplementary angles.
Supplementary angles are commonly found in geometry and trigonometry. For example, in a right triangle, the two acute angles are always complementary (they add up to 90 degrees), and the hypotenuse and one of the acute angles are always supplementary (they add up to 180 degrees).
Supplementary angles can also be used to solve problems involving unknown angles. For instance, if you know that two angles are supplementary and you know the measure of one of the angles, you can use algebra to solve for the measure of the other angle.
