the equation a = represents the angle measures, a, in a regular n-sided polygon. when the equation is solved for n, n is equal to a fraction with a denominator of a – 180. what is the numerator of the fraction?
a = 180(n - 2)
a = 180n - 180*2
a = 180n - 360
180n - 360 = a
180n = a + 360
n = (a + 360) / 180
Numerator for fraction above = ( a + 360), denominator = 180
