Question

Find the sum of the interior angles of a 12-sided polygon.


a) 1,080°

b) 1,800°

c) 2,100°

d) 2,160°

Answer 1

The formula for the sum of the interior angles of a polygon with n sides is (n-2) * 180°.

Plugging in n = 12, we get (12-2) * 180° = 10 * 180° = 1800°.

Therefore, the sum of the interior angles of a 12-sided polygon is 1,800°.

The correct answer is (b) 1,800°.
