Question

Find the complement of the following angle:
${40}^{\circ }$

Answer 1

Finding the complement of ${40}^{\circ }$:

1. When the sum of the two angles is equal to ${90}^{\circ }$, the two angles are said to be complimentary.
2. The complement angle can be found by subtracting the given angle from ${90}^{\circ }$.

The complement angle of ${40}^{\circ }$,
$={90}^{\circ }-{40}^{\circ }$
$={50}^{\circ }$
So, the complement angle of ${40}^{\circ }$ is ${50}^{\circ }$.
