Homework Statement
How many sides does a polygon have if the measure of each interior angle is 8 times the measure of each exterior angle?
Homework Equations
Interior angle of a polygon: ((n-2) * 180)/n
Exterior angle of a polygon: (360)/n
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.
