Question
If the exterior angle of a regular polygon measures 30°, how many sides does it have?Question 51Select one:a.15b.12c.7d.9
Solution
The formula to find the number of sides of a regular polygon is n = 360° / measure of one exterior angle.
Given that the measure of one exterior angle is 30°, you can substitute this value into the formula:
n = 360° / 30° = 12
So, the regular polygon has 12 sides. Therefore, the correct answer is b.12.
