what is the angle of rotation for a regular nonagon?

jimthompson5910 (jim_thompson5910):

How many sides are in a regular nonagon?

OpenStudy (anonymous):

im not sure

jimthompson5910 (jim_thompson5910):

a nonagon has 9 sides

jimthompson5910 (jim_thompson5910):

In general, the angle of rotation of a regular polygon with n sides is 360/n

OpenStudy (anonymous):

so what do you think the answer is ?

jimthompson5910 (jim_thompson5910):

What is the value of n in this case?

OpenStudy (anonymous):

9?

jimthompson5910 (jim_thompson5910):

So 360/n = 360/9 = ???

OpenStudy (anonymous):

40 ?

jimthompson5910 (jim_thompson5910):

good, so the angle of rotation is 40 degrees
