Find the supplement of the following angle:
$$123^\circ$$


SOLUTION
Two angles are said to be supplementary if the sum of their measures is $$180^\circ.$$
The given angle is $$123^\circ$$
Let the measure of its supplement be $$x^\circ$$.
Then,
$$ \implies x + 123 = 180$$
$$ \implies x = 180 - 123$$
$$ \implies x = 57^\circ$$
Hence, the supplementary of the given angle measures $$57^\circ.$$
