Each angle measure of a regular polygon is 60°. what is the polygon?

Triangle

Step-by-step explanation:

A regular polygon of n sides has interior angles of:

a = 180 (n-2) / n

Given a = 60:

60 = 180 (n-2) / n

n = 3 (n-2)

n = 3n - 6

6 = 2n

n = 3

The polygon has three sides, so it's a triangle.

the answer is b.
