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.
