You can put this solution on YOUR website! The interior angles of a convex nonagon have degree measures that are integers in arithmetic sequence. What is the smallest angle possible in this nonagon?
===============
Exterior angles of a regular nonagon are 360/9 = 40 degrees
--> interior angles = 140 degs
--------
For the 9 angles, 140 is the average
--> 136,137,138,139,140,141,142,143,144 degs
