Question

How many sides does a regular polygon have if each exterior angle measures 30° ?

Answer 1

The sum of the measures of the extrior angles of a polygon, taken one per vertex, is 360. This is true no matter how many sides the polygon has.

Answer 2

I don;t get it. My answer choices are a.
14 sides
b.
12 sides
c.
15 sides
d.
11 sides

Answer 3

Since the sum of all exterior angles is 360, and all angles are congruent (regular polygon), just divide 360 by 30.
