For this case we must simplify the following expression:
[tex]\frac {(n-2) 180} {n}[/tex]
We apply distributive property to the terms within parentheses:
[tex]\frac {180n-360} {n} =[/tex]
[tex]\frac {180n} {n} - \frac {360} {n} =\\180- \frac {360} {n}[/tex]
Thus, the simplified expression is:
[tex]180- \frac {360} {n}[/tex]
Answer:
[tex]\frac {(n-2) 180} {n} = 180- \frac {360} {n}[/tex]
