A ten-sided polygon. The sum of the angles of a decagon is 1440°. so 1440°÷10=144°

----------------------------------------------------------------------------

The easiest way to calculate this is to calculate the exterior angle and use the fact that the exterior and interior angles are supplementary.

Sum exterior angles = 360°

→ Each exterior angle of a regular decagon is 360° ÷ 10

→ Each interior angle of a regular decagon = 180° - 360° ÷ 10 = 144°

Each interior angle of a regular decagon is 144 degrees

well the total degrees in a decagon is 1440 therefore each interior angle in a regular decagon would measure 144 degrese

Sum of the interior angles of a decagon = 180*(10-2) = 180*8 = 1440 degrees. Since each interior angle of a regular polygon has the same measure, each angle of the decagon = 1440/10 = 144 degrees.

Each interior angle of a regular decagon would measure 144 degrees,

Sum of the interior angles of a decagon = 180*(10-2) = 180*8 = 1440 degrees. Since each interior angle of a regular polygon has the same measure, each angle of the decagon = 1440/10 = 144 degrees.

The angle measure for each interior is 144 degrees each.Explanation: The angle measure of each interior angle of a regular decagon is 144°. Since a decagon is a 10-sided figure, replace n by 10 in (n − 2) • 180°. So the sum of the interior angle measures in a decagon is (10 − 2) • 180°, or 8 • 180° = 1440°. This is a regular decagon, so all ten interior angles are congruent. To calculate the measure of each interior angle in this regular decagon, divide 1440 by 10. The answer is 144°. 144 degrees is equal to 4/5 of 180 degrees
