Sagot :
Given Information :-
⠀
- Each exterior angle of a regular polygon has a measure of 40°
⠀
To Find :-
⠀
- The number of sides of the polygon
⠀
Formula Used :-
⠀
[tex] \qquad \star \: \underline{ \boxed{ \green{ \sf No.~of~sides = \dfrac{360^ \circ}{exterior ~angle}}}} \: \star[/tex]
⠀
Solution :-
⠀
Using the formula,
⠀
[tex] \sf \dashrightarrow No. ~of~sides= \dfrac{360}{40} \\ \\ \\ \sf \dashrightarrow No. ~of~sides= \frac{ \cancel{360}}{ \cancel{40} } \\ \\ \\ \sf \dashrightarrow No. ~of~sides= \underline{ \boxed{ \blue { \frak{9}}}} \: \star[/tex]
⠀
Thus, the polygon is a nonagon, and hence has 9 sides.
⠀
[tex] \underline{\rule{227pt}{2pt}} \\ \\ [/tex]
