Answer:A polygon with 8 sides called octagon

Step-by-step explanation:

sum of interior angles in a polygon=180(n-2)

n=number of sides

1080=180(n-2)

Divide both sides by 180

1080/180=180(n-2)/180

6=n-2

Collect like terms

n=6+2

n=8

number of sides=8

Fractional index means "xth root of". Negative index means a fraction. So together, what it really means is:

$\frac{1}{\sqrt[5]{32}} = \frac{1}{2}.$
