the equation a= 180(n-2)/n 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 = angle measures Do you mean the measure of one angle in the polygon or the total measure of all the angles?

    an = 180n - 360 an - 180n = -360 can you continue?

    no factor an - 180n = n(a-180) = -360 now you divide both sides by a - 180
