the interior angle of a 7 sided regular polygon is 128.57 degrees
== ==
(24-2)*180 = 3960 degrees
The sum of the internal angles of an n-sided polygon is (n-2)*180 degrees. So, for a regular polygon, each internal angle is (n-2)*180/n degrees.
A 29-sided polygon.
It's 900 degrees, and it doesn't matter whether the 7-sided polygon is regular or not.
Sum of exterior angles of any sided polygon is 360 so sum of exterior angle of 6 sided polygon (hexagon) is 360
If a dectagon is another word for a decagon then this is a 10 sided polygon. No matter how many sides it has, the sum of the external angles of a convex or regular polygon is 360°.

The sum of the interior angles of a 14 sided polygon are 2160 degrees.
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
