Write the supplement of each of the following angles:$138^o$

Given:

The given angle is $138^o$.

To do:

We have to find the supplement of the given angle.

Solution:

An angle is said to be the supplement of another angle if the sum of both the angles is $180^o$.

If $x$ is an angle, then its supplement is $180^o - x$.

Therefore,

Supplement of $138^o = 180^o - 138^o$

$=42^o$

Hence, the supplement of $138^o$ is $42^o$.
