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

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. \(\Large \color{MidnightBlue}{\Rightarrow {180n - 360 \over n} = 60 }\) \(\Large \color{MidnightBlue}{\Rightarrow 60n = 180n - 360 }\) \(\Large \color{MidnightBlue}{\Rightarrow 0 = 120n - 360 }\) \(\Large \color{MidnightBlue}{\Rightarrow 360 = 120n }\) \(\Large \color{MidnightBlue}{\Rightarrow n = 3 }\)
