Finding Sides of a Regular Polygon

Hard Geometry And Measurement Polygons

Consider a regular polygon with n sides, where n is an integer greater than 2. The formula for finding the measure of each interior angle of a regular polygon is given by:

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

Suppose the measure of each interior angle of a regular polygon is 150 degrees. What is the number of sides, n, of this polygon?
