Answer:
40° and 9°
Step-by-step explanation:
The sum of the exterior angles of a polygon = 360°
If the polygon is regular then the measure of each exterior angle is
[tex]\frac{360}{n}[/tex] ← where n is the number of sides
(a) for a regular 9 sided polygon
exterior angle = [tex]\frac{360}{9}[/tex] = 40°
(b) for a regular 40 sided polygon
exterior angle = [tex]\frac{360}{40}[/tex] = 9°
