Answer:
No, since is not a whole number
Sum of exterior angles of regular polygon is 360°
When we divide the exterior angle by 360°, we get the numbers of exterior angle. Since, it is a regular polygon number of exterior angles will be equal to number to sides.
N = 360/50 = 7.2 [Number of sides of polygon]
7.2 is not an integer. So, it is not possible to have a regular polygon whose each exterior angle is 50°.
