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.
