# 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 $57^\circ.$
