Question

(a) An angle measures 81°. What is the measure of its supplement? (b) An angle measures 61. What is the measure of its complement? 2 measure of the supplement: X 5 ? measure of the complement:

Answer 1

We call the supplement of 81° as x, so:

$\begin{gathered} 81+x=180 \\ x=180-81=99 \end{gathered}$

The supplement of 81° is 99°.

We call the complement of 61° as y, so:

$\begin{gathered} 61+y=90 \\ y=90-61=29 \end{gathered}$

The complement of 61° is 29°
