AnswerIt is Dodecagon.To find this, you have to first find the exterior angle of the polygon. Since the exterior angle of a polygon is always supplementary to the interior angle, you subtract the measure of the interior angle from 180. 180-150=30. Now You divide 360 by the measure of the exterior angle to get the number of sides of the polygon. 360/30=12. A 12-sided polygon is called a dodecagon
If the polygon is a regular polygon then all interior angels are equal to 180-(360/no of sides of the polygon)
It will have 10 equal sides

The sum of the interior angles of an n-sided polygon is 180n - 360 degrees.
144 degrees
a 7 sided polygon is heptagon and the interior angle of it is 128.57 degrees.
