Question

The sum of the interior angle of a polygon is 1260 degrees. How many sides does the polygon have?

Answer 1

Answer: 9 sides

Explanation:

If this is a perfect polygon then the answer is 9 sides. A perfect polygon is a polygon where all the sides and angles are congruent to each other.

180°(n-2) = 1,260°

n - 2 = 7

n = 9
