The equation a=180(n-2)/n represent 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.

The

numerator is 360

Step-by-step explanation:

What we need to do here is make n the subject of the formula;

a = 180(n-2)/n

an = 180n-360

180n - an = 360

n(180-a) = 360

n = 360/(180-a)

Correct -360

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
