The sum of interior angles of any N-sided polygon is: N*180° - 360°. For N = 10, this gives 1440°. Since the decagon is regular, all angles are equal, and each angle is 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.
144 degrees
144 degrees is.
