Question

Find the complement angle of $45°$ .

Answer 1

Finding the complement angle

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

Let the unknown angle is $=x$

Then,

$$\begin{gathered} 45°+x=90° \\ \Rightarrow x=90°-45° \\ \Rightarrow x=45° \end{gathered}$$

Hence, complement angle of $45°$ is $45°$
