Question 1066598
Regular convex polygons have exterior angles that add up to 360 degrees, and all the angles are congruent (congruent means they are identical)
:
So in your problem, the polygon has exterior angles of 30 degrees. Les't solve this:
Sum of the angles of a polygor: 360
Number of sides of the polygon: n
Each exterior angle: 30 degrees
30n = 360 divide both sides by 30
n = 12 your polygon has 12 sides
