Correct Answer

Explanation

Exterior angles =180-150=30n=360/30n=12A regular polygon with an interior angle of 150 degrees would have 12 sides. The formula to find the number of sides in a regular polygon is: n = 360° / AWhere n is the number of sides and A is the measure of each interior angle. Applying this formula, we get:n = 360° / 150° = 12Therefore, a regular polygon with an interior angle of 150 degrees would have 12 sides.
