Exterior angles of ANY polygon add to 360 degrees. Individual angles are therefore 360/n where n is the number if sides.

The largest exterior angle measure is 120o. It is the exterior measure of an equilateral triangle (which is a regular polygon).
Providing that it is a regular polygon then each exterior angle will measure 12 degrees
Exterior angle of ANY regular n-sided polygon is 360/n degrees, in this case 360/12 ie 30o
The measure of an interior angle in degrees of a regular polygon of n sides is given by the formula: 180 x (n-2) / nSubstituting with n=15, then the answer is thatthe interior angle = 12x13 =156The measure of an exterior angle in degrees of a regular polygon of n sides is given by the formula: 360/nSubstituting with n= 15, then the answer is that the exterior angle = 24
Interior angle 156 degrees Exterior angle 24 degrees 360/24 = 15 sides
