(a) an angle measures 43 . what is the measure of its complement? (b) an angle measures 81 . what is the measure of its supplement?

To solve the problem shown above, you must follow the proccedure shown below:

 1. By definition, Completary angles are those angles whose sum is 90 degrees and Suplementary angles are those angles whose sum is 180 degrees.

2. Keeping the information above on mind, you have:

 (a) An angle measures 43 . What is the measure of its complement?

 =90°-43°
 =47°

 (b) An angle measures 81 . What is the measure of its supplement?

 =180°-81°
 =99°

 The answers are:

 a) 47°
 b) 99°
