Find the number of sides of a regular convex polygon whose angle is 40degrees.
Read Solution (Total 3)
-
- for n sided regular polygon, central angle is given by (360 degree / n)
given (360/n)=40, therefore n=(360/40)=9 - 14 years agoHelpfull: Yes(20) No(5)
- measure of interior angle=180-360/n=2.5
hence nt possible - 14 years agoHelpfull: Yes(7) No(5)
- we know total angle of any polygen is=(n-2)*180
n=no of side
then according ques (n-2)*180=40*n
n=18/7
whish is not possible - 13 years agoHelpfull: Yes(3) No(0)
