The exterior angle sum is 360 degrees. It doesn't matter whether the polygon
is regular or not, and it doesn't even matter how many sides it has.
360 ________________________________________________ Sum of Interior Angles of a Polygon = 180 (n-2) Sum of Exterior Angles of a Polygon = 360 The sum of an angle and an exterior angle of a regular polygon is 360
Interior Angle: 150 degrees (Interior Angle Sum: 1800) Exterior Angle: 30 degrees (Exterior Angle Sum: 360)
For any polygon, regular or otherwise, the sum of exterior angles is always 3600.
The exterior angles of a REGULAR 15-gon are 204o, so the sum would be 3060o. This remains true for non-regular 15-gons as well (the exterior angle sum, not the exterior angles).
If the heptagon is regular the angle measurement for three angles would be approximately 385.7
The sum of the exterior angles of an n-gon is 360 degrees, however many sides it has.
Each angle is about 51.43 degreesheptagon=7 sides, 7 anglesexterior angles sum=360360/7= about 51.4285

Interior Angle: 150 degrees (Interior Angle Sum: 1800) Exterior Angle: 30 degrees (Exterior Angle Sum: 360)
For any polygon, regular or otherwise, the sum of exterior angles is always 3600.
The 7 interior angles of a heptagon add up to 900 degrees
The exterior angles of a REGULAR 15-gon are 204o, so the sum would be 3060o. This remains true for non-regular 15-gons as well (the exterior angle sum, not the exterior angles).
