The sum of the interior angles of regular polygon is 1800o. How many sides has the polygon?
Answer Details
The sum of the interior angles of a polygon can be found by the formula:
sum of interior angles = (n-2) x 180 degrees
where n is the number of sides in the polygon.
In this problem, we are given that the sum of the interior angles of the polygon is 1800 degrees. So we can set up an equation:
1800 = (n-2) x 180
Simplifying the equation:
10 = n - 2
n = 12
Therefore, the polygon has 12 sides.
