How many sides does a polygon have if sum of its interior angles is 3780⁰?
Open in App
Solution
Sum of interior angles of a polygon = (n-2)*180⁰
So,
(n-2)*180⁰ = 3780⁰
(n-2) = 3780/180 = 21
n = 23
Therefore the polygon has 23 sides.
So,
(n-2)*180⁰ = 3780⁰
(n-2) = 3780/180 = 21
n = 23
Therefore the polygon has 23 sides.
