This figure is a regular 12-sided polygon. Find m<4
Central angle

Each central angle is (360) divided by (number of sides in the polygon).
Each side subtends a central angle of 30 degrees.

To calculate the measure of a central angle of a regular nine-sided polygon, divide 360 degrees by the number of sides. In this case, divide 360 by 9. The measure of the central angle of a regular nine-sided polygon is 40 degrees.

The central angle of a n-sided regular polygon = 360 degrees / n. Hence, the central angle of a 15-sided regular polygon = 360 degrees / 15 = 24 degrees ============================
