if a regular polygon has 24 sides, what is the measure of each exterior angle of the polygon?
Each exterior angle measures 15°.
How to see it
For any regular polygon, the sum of all exterior angles is 360°.
If the polygon has 24 equal exterior angles, then each one is
exterior angle=360∘24=15∘\text{exterior angle}=\frac{360^\circ}{24}=15^\circ exterior angle=24360∘=15∘
So a regular 24-sided polygon has exterior angles of 15° each.
