What is the measure of each interior angles of a regular 125-gon?

To find the measure of each interior angle of a regular polygon, we use the formula: (n-2) * 180 / n, where n is the number of sides of the polygon. In this case, a regular 125-gon has 125 sides. So, each interior angle would measure (125-2) * 180 / 125 = 172.8 degrees.
