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
Theorem 6-1-2; Polygon Exterior Angle Sum Theorem:The sum of the exterior angle measures, one angle at each vertex, of a convex polygon is 360 degrees.
51.428571° is the measure of an exterior angle of a heptagon. You can always find the measurements of a regular polygon by dividing 360 by the amount of sides.
The sum total of all exterior angles of any polygon is 360 degrees. So if you're given thevalue of one exterior angle AND THE POLYGON IS REGULAR(all exterior angles are thesame size), all you have to do is divide the size of one angle into 360, and the quotientis the number of sides.
The sum of the exterior angles of a 2D planar polygon is always 360 degrees.
180-interior angle = exterior angle If it's a regular polygon then: 360/number of sides = exterior angle
An exterior angle of a polygon is the supplement of the corresponding interior angle. The exterior angle is the angle between an extended sides of the polygon and the next side of the polygon.
By dividing number of its sides into 360 will give you the exterior angle.
Any irregular polygon can have an exterior angle measuring 60 degrees.Any irregular polygon can have an exterior angle measuring 60 degrees.Any irregular polygon can have an exterior angle measuring 60 degrees.Any irregular polygon can have an exterior angle measuring 60 degrees.

If it is a regular polygon then divide the exterior angle into 360 degrees to find the amount of sides it has because the exterior angles of any polygon add up to 360 degrees.
180 minus interior angle = exterior angle because there are 180 degrees on a straight line
The exterior angles of any polygon add up to 360.
180 - interior angle = exterior angle
The interior angle of a polygon and its adjacent exterior angle can never be complementary.
