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°
