The sum of the exterior angles of any polygon is 360 degrees.

For a regular decagon (10 sides), the measure of each exterior angle is 360/10 degrees.

.

Decagon has 10 sides.


The sum of the interior angles of any convex polygon is  (n-2)*180  degrees, where n is the number of sides.



THEREFORE, for the regular decagon, the sum of its interior angles is  

     degrees = 8*180 degrees = 1440 degrees.



Hence, each individual interior angle is  1400/10 = 144  degrees.    ANSWER

Solved.
