OpenStudy (vishal_kothari):

how could it will be 60?

OpenStudy (vishal_kothari):

60*3=180

OpenStudy (anonymous):

OH NO!! I am sorry. I was doing 60 degrees for each interior angle of the triangle with the center of the polygon.

OpenStudy (anonymous):

Sum of interior = 720 Individual angle = 720/6 = 3x = 120 x = 30

OpenStudy (ash2326):

Sum of interior angles (n-2)*180 it's a hexagon n=6 4*180=720 6*3x=720 x=40 degress

OpenStudy (anonymous):

Yeah, I know that 3x=120 degrees.

OpenStudy (vishal_kothari):

good
