Question

Find the supplement of following angles:

$57°$

Answer 1

Supplement angles are angles which add up with other angle to form $180°$.

Let the supplement angle be $x°$

Then,

$$\begin{gathered} 57°+\angle x=180° \\ \angle x=180°-57° \\ \angle x=123° \end{gathered}$$

Hence, the complement of $57°$ is $123°$.
