Interior Angles of a Regular Dodecagon

Very Hard Geometry Polygons

Consider a polygon with 12 sides (a dodecagon). Each interior angle of a regular dodecagon can be calculated using the formula for the interior angle of a regular polygon, which is given by:

$$ ext{Interior Angle} =\frac{(n - 2) imes 180}{n}$$

where $n$ is the number of sides of the polygon. What is the measure of each interior angle in degrees for a regular dodecagon?
