Calculate the number of sides of a polygon whose sum of angles is 1800°

Answer 1

The formula to calculate the sum of the interior angles of a polygon is: (n-2) * 180, where n is the number of sides of the polygon.

Given that the sum of angles is 1800°, we can set up the equation:

(n-2) * 180 = 1800

Solving for n:

(n-2) = 1800 / 180
n-2 = 10
n = 10 + 2
n = 12

Therefore, the polygon has 12 sides.
