Divide the 360 by 10
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 is 150 degrees
Each interior angle measures 140 degrees
Each interior angle: 1640 20' 52.17''
Each interior angle is: 1540 17' 8.57''
Each interior angle is 144 degrees.
Each interior angle measures 144 degrees

In a general decagon an interior angle can have any value in the range (0, 360) degrees - excluding 180 degrees. The only constraint is that the sum of all interior angles must be 1440 degrees.
