Question

Write the complement of angle $13°$.

Answer 1

Given angle: $13°$.

We know that If the sum of the two angles is $90°$, the angles are said to be complementary angles and each angle said to be the complement of the other.

Let $\mathrm{x}°$ be a complement of angle $13°$.

Then,

$$\begin{gathered} \mathrm{x}°+13°=90° \\ \Rightarrow \mathrm{x}°=90°-13° \\ \Rightarrow \mathrm{x}°=77° \end{gathered}$$

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