A side length of a regular nonagon is an integer. The perimeter of the nonagon is 80 when rounded to the nearest ten. Determine the integer side length.

Step-by-step explanation:

A nonagon is a shape with 9 sides. A regular shape means that all angles and sides of the shape is equal. That means let call the side of the nonagon, n. That means the perimeter which is 80, which means all side, n will add up.

or

Solve for n

This rounded would make our interger side, 9

after going and makeing graphs i would go with a,

there is nothing that is matches the graph. if there was i would show you. but therefore my answer is a.

hope i
