The formula to find one interior angle is: $$\Large \color{MidnightBlue}{\Rightarrow {180n - 360 \over n} }$$ n is the number of sides. $$\Large \color{MidnightBlue}{\Rightarrow {900 - 360 \over 5} }$$ $$\Large \color{MidnightBlue}{\Rightarrow {540 \over 5} }$$ $$\Large \color{MidnightBlue}{\Rightarrow 108 }$$ The sum of an interior and exterior angle is 180. 108 + exterior = 180 exterior = 108 - 180 exterior = 72
