Answer 1

Answer :-

• 40° is the answer

Question :-

$\rm \: Find \: the \: measure \: of \: each \: exterior \: angle \: of \: a \: regular \: polygon \: of \: (a) \: 9 \: sides.$

To solve we need to know ?

To solve the following we need to know a formula that is :-

$\rm\rightarrow{ \huge(}\dfrac{360°}{n}{ \huge)}$

*Here n represents No. of sides .

• No. of sides here → 9 sides

Now, simply putting the No. of sides in n and finding out :-

$\mapsto{\huge(}\dfrac{360°}{9}{ \huge)}^{°}$

$\mapsto{\huge(} \cancel\dfrac{360°}{9}{ \huge)}^{°}$

$\mapsto \bf40°\star$

$\sf \therefore Measure \: of \: each \: exterior \: angle \: of \: a \: regular \: polygon \: of \: 9 \: sides \: is \: \bf40°$
