Question

For a regular 30-sided polygon, what is the degree of rotation?

Answer 1

The measure of any interior angle of a convex regular n-gon is :
180 º - ( 360 º / n )

For a 30-sided polygon,
interior angle = 180 º - ( 360 º / 30 )
..................... = 180 º - 12 º
..................... = 168 º

Answer 2

the degree would be 83
