Question

Identify the sum of the angle measures in a decagon (a 10-sided polygon)

O 1800°
0 1440°
0 1620°
O 1260°

Answer 1

1440 degrees

Explanation:

formula for calculating sum of angles in a polygon is (n-2) 180 where n is 10 that's 10-2 which is 8 and 8 * 180 which is 1440

Answer 2

1440°

Explanation:

(n - 2)180° - (10 - 2)180° = 8(180°) = 1440°
