need help with unit 7 homework 1

Answer:
16 sides.
Explanation:
Question 7.
we know the formula that gives us exterior angle:
[tex]\frac{360}{n}[/tex] .........here n is number of sides.
so,
[tex]\frac{360}{n} = 22.5[/tex]
n = [tex]\frac{360}{22.5}[/tex]
n = 16 sides
Therefore the polygon has 16 sides.
