(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

How many sides does a polygon have if the measure of each interior angle is 8 times the measure of each exterior angle?

2. Relevant equations

Interior angle of a polygon: ((n-2) * 180)/n

Exterior angle of a polygon: (360)/n

3. The attempt at a solution

((n-2) * 180)/n = 8 * (360)/n

now ((n-2) * 180) = 8 * 360

180 n -360 = 8 * 360

180 n = 7 * 360

n = 14

I am getting n = 14 which is wrong.

Some body please guide me what is the problem.

Zulfi.
