S = 180(n - 2) \\ S = 180n - 360 \\ 180n =( S + 360) \\ n = ((S+ 360))/(180)

where, n =number of sides of polygon

S =sum of the degree measures of the interior angles of the polygon

Answer:

  • n = (S + 360)/180

Explanation:

Given formula:

  • S = 180(n - 2)

Solving for n:

  • S = 180(n - 2) ⇒ open parenthesis
  • S = 180n - 360 ⇒ isolate n
  • 180n = S + 360 ⇒ divide both sides by 180
  • n = (S + 360)/180
