Answer
$120$
Work Step by Step
The measure of an interior angle of a polygon is given by the following formula:
m of an interior angle = $\frac{(n - 2)(180)}{n}$, where $n$ is the number of sides in the polygon.
A hexagon has six sides, so we plug this information into the formula to find the measure of one of its interior angles:
m of an interior angle = $\frac{(6 - 2)(180)}{6}$
Evaluate parentheses first:
m of an interior angle = $\frac{(4)(180)}{6}$
Multiply first:
m of an interior angle = $\frac{720}{6}$
Divide to solve:
m of an interior angle = $120$
