When I was in 6th grade I came up with an equation for finding the measure of the interior angle of any vertex to a regular polygon.

where is the number of sides to the polygon. My equation comes out in degrees.

But you guys are saying which comes out in radians.

Wouldn't it just be easier to say ?

P.S. I know the equations are the same, one just comes out in radians and the other in degrees; My main question is what is the point of radians?
