Question

Find the complement of following angles:

$13°$

Answer 1

Complement angles are angles which add up with other angle to form $90°$.

Let the complement angle be $x°$

Then, $$\begin{gathered} 13°+x=90° \\ \angle x=90°-13° \\ \angle x=77° \end{gathered}$$

Hence, the complement of $13°$ is $77°$.
