In a regular polygon, each interior angle doubles its corresponding exterior angle. Find the number of sides of the polygon.
- 8
-
6
- 4
- 3
The correct answer is: B
Explanation
2x + x = 180°, => 3x = 180°, and thus x = 60°Each exterior angle = 60° but size of ext. angle = 360°/n
Therefore 60° = 360°/n
n = 360°/60° = 6 sides
