Question

Find the complement angle of $50°$.

Answer 1

Find the complement angle:

Complement angle : Two angles are called complementary when their measures add to $90°$.

Let the unknown angle is $=x$

Then

$$\begin{gathered} 50°+x=90° \\ x=90°-50° \\ x=40° \end{gathered}$$

Hence, complement angle of $50°\text{is}40°$.
