Since the interior angle measure of the regular polygon is 140⁰, its exterior angle measure is 180⁰ - 140⁰ = 40⁰. Since the sum of the exterior angle measures is 360⁰, the polygon has 360⁰/40⁰ = 9 sides.
140 degrees is an obtuse angleAn angle of 140 degrees would be called obtuse.
It can be any size at all, between zero and 360 degrees.If the nonagon is regular, then the angle measures 140 degrees.
If the interior angle = 140 degrees, then the exterior angle = 180 degrees - 140 degrees = 40 degrees. So the number of sides is 360 degrees / 40 degrees = 9 sides (a nonagon).
40 degrees ( 180 - 140 = 40 )
