If the exterior angle is 30o then the shape has 360/30 = 12 sides.
An interior angle = 180 - exterior angle = 180 - 30 = 150.
Since the shape has 12 sides the interior angles sum to 150 x 12 = 1800o.
The sum of the exterior angles of a regular polygon = 360° If an exterior angle measures 8° then the number of sides = 360/8 = 45

The sum of the exterior angles of a regular polygon equal 360° . If one such angle measures 36° then the polygon has 360/36 = 10 sides.
The exterior angles of any polygon add up to 360.
There are 18 sides.
1260 degrees
There is no such thing as an exterior polygon. "Exterior" means outer. Polygons can have exterior angles, but that is about it!A regular polygon can have 3 or more sides - up to infinitely many.There is no such thing as an exterior polygon. "Exterior" means outer.

The sum of a regular polygons exterior angles always = 360
The number of sides in a regular polygon can be determined by dividing 360 degrees (the sum of all exterior angles in any polygon) by the measure of each exterior angle. In this case, if each exterior angle measures 30 degrees, the polygon will have 12 sides.
Hint: in a regular polygon interior plus exterior = 180o, always.
360 degrees and the polygon is an equilateral triangle.
How many sides does a regular polygon have if each exterior angle measures 20?
The sum of the measures of the exterior angles of any polygon, regular or irregular, is always 360 degrees. In a regular polygon with ten sides, each exterior angle measures 360 degrees divided by the number of sides, which in this case is 36 degrees. Therefore, the sum of the measures of the exterior angles of a regular decagon is 10 multiplied by 36 degrees, which equals 360 degrees.
An equilateral triangle is the only polygon in which the exterior angle is larger than the interior angle. They are equal in a square and smaller in all regular polygons with more sides,
