Answer:
Step-by-step explanation:
The formula for exterior angles of a regular polygon is that they must add up to 360. They are also equal for a regular polygon.
Exterior angle = 360 / number of sides
The first one (a pentagon) has 5 sides
Exterior angle = 360/5
Exterior angle = 360/5 = 72
The second one has 8 sides.
Exterior angle = 360/8
Exterior angle = 360/8 = 45
