PROBLEM:

The sum of the measures of the interior angles of a convex polygon is 1980 degree find the number of the sides of the polygon.

[tex]\underline{\mathcal{REMEMBER:}}[/tex]

  • Sum of interior angles = (n - 2)180

[tex]\underline{\sf{Solution:}}[/tex]

  • (n - 2)180 = 1980
  • n - 2 = 1980/180
  • n - 2 = 11
  • n = 11 + 2
  • n = 13

[tex]\underline{\sf{Answer:}}[/tex]

  • The no. of sides of a polygon is 13 sides.
