# Find the complement of the following angle:$60^\circ$

##### SOLUTION
Two angles are said to be complementary if the sum of their measures is $90^\circ.$
The given angle is $60^\circ$
Let the measure of its complement be $x^\circ.$
Then,
$\implies x + 60 = 90$
$\implies x = 90 - 60$
$\implies x = 30^\circ$
Hence, the complement of the given angle measures $30^\circ$.
