Interior Angle of a Hexagon

In a geometry class, students are studying properties of different polygons. One student is working on a hexagon, defined as a polygon with six sides.

She draws a regular hexagon, where all sides are of equal length and all angles are equal. She measures one interior angle and remembers that the formula for finding the measure of an interior angle of a regular polygon is:

$$ ext{Interior angle} =\frac{(n-2) imes 180^ ext{o}}{n} $$

where $n$ is the number of sides of the polygon. Using this formula, what is the measure of one interior angle of a regular hexagon?
