Answer 2

SOLUTION :

$1) \: the \: number \: of \: sides \: of \: n \: sided \: polygon \: = \frac{360}{n} \\ \\ given \: each \: exterior \: angle \: of \: polygon \: = 72 \\ \\ = > \frac{360}{n} = 72 \\ \\ = > n = \frac{360}{72} = 5 \\ \\ thus \: number \: of \: sides \: of \: regular \: polygon \: is \: 5 \\ \\ 2)given \: number \: of \: sides \: of \: polygon \: = 8 \\ \\ measure \: of \: each \: exterior \: angle \: = \frac{360}{n} \\ \\ = \frac{360}{8} = 45 \\ \\ measure \: of \: each \: exterior \: angle \: of \: \\ octagon = 45 \\ \\ 3) \: sum \: of \: interior \: angles \: of \: \\ a \: polygon \: = (n - 2)180 \\ \\ = > sum \: of \: interior \: angles \: \\ of \: 24 \: sided \: polygon \: = 22(180) = 3960$
