The measure of each interior angle of a fifteen sided regular polygon, a pendedecagon, is 156o.
The interior angle of an octdecagon, an 18 sided regular polygon, is 160o.
The measure of 1 exterior angle of a regular 8-sided polygon is equivalent to 45 degrees. Hope I helped! :)
Each central angle of a regular 9 sided polygon: 360/9 = 40 degrees
This figure is a regular 12-sided polygon. Find m<4

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 ============================
51º per interior angle
the center angle of any polygon is 360 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.
