Find the number of sides of a regular polygon whose each exterior angle has a measure of 72°.

Step-by-step explanation:

The sum of the exterior angles of a polygon = 360°

The formula for calculating the size of an exterior angle is:

exterior angle of the polygon = 360 ÷ n

(where n is the number of sides)

Therefore,                            72 = 360 ÷ n

Multiply both sides by n:   72n = 360

Divide both sides by 72:         n = 5

Therefore, a polygon whose exterior angle has a measure of 72° has 5 sides.

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8

days of the week

step-by-step explanation:

javier earned more money then kyle, so that won't always be a constant term, but the days of the week do not change so that term is always constant.
