Find the number of sides of a regular polygon if one interior angle is 60 degrees. 3 4 5 6 OpenStudy (anonymous):

Let the number of sides be n 180(n-2)=(n)60 solve for n. Parth (parthkohli):

As I said, the formula to find one interior angle is: $$\Large \color{MidnightBlue}{\Rightarrow {180n - 360 \over n} }$$ Here, one interior angle is 60 degrees. $$\Large \color{MidnightBlue}{\Rightarrow {180n - 360 \over n} = 60 }$$ $$\Large \color{MidnightBlue}{\Rightarrow 60n = 180n - 360 }$$ $$\Large \color{MidnightBlue}{\Rightarrow 0 = 120n - 360 }$$ $$\Large \color{MidnightBlue}{\Rightarrow 360 = 120n }$$ $$\Large \color{MidnightBlue}{\Rightarrow n = 3 }$$ OpenStudy (anonymous):

again the same formula? OpenStudy (anonymous):

okay i think im getting there Parth (parthkohli):

Yep :D OpenStudy (anonymous):
