What is the sum of the interior angle measures of a 20-gon? (1 point) Responses 360o 360 o 3,240o 3,240 o 3,600o 3,600 o 162o
The sum of the interior angles in any polygon can be found using the formula: (n-2) * 180, where n is the number of sides of the polygon.
For a 20-gon, n = 20, so the sum of the interior angle measures is (20-2) * 180 = 18 * 180 = 3,240.
Therefore, the answer is 3,240o.
