Question

how many sides does a regular polygon has if the measure of an exterior angle is 45°​

Answer 1

Answer:

We do this by dividing 360° by the number of sides, which is 8. (b) Calculate the size of each interior angle in the regular octagon. We do this by subtracting the size of each exterior angle, which is 45°, from 180°. A regular polygon has equal exterior angles of 72°.
