(i) Sum of all exterior angles of the given polygon = 360 º

Each exterior angle of a regular polygon has the same measure.

Thus, measure of each exterior angle of a regular polygon of 9 sides

= \( \frac{360^\circ}{9} = 40^\circ\)

(ii) Sum of all exterior angles of the given polygon = 360 º

Each exterior angle of a regular polygon has the same measure.

Thus, measure of each exterior angle of a regular polygon of 15 sides

= \( \frac{360^\circ}{15} = 24^\circ\)
