Question

How many sides does regular polygon have if each of its interior angle measure the following?

a. 150°​

Answer 1

Answer:

Since an interior angle is 150 degrees, its adjacent exterior angle is 30 degrees. Exterior angles of any polygon always add up to 360 degrees. With the polygon being regular, we can just divide 360 by 30 to get 12 sides.

SO THE ANSWER IS 12 SIDES
