Find the number of sides of a regular convex polygon whose angle is 40degrees.

• for n sided regular polygon, central angle is given by (360 degree / n)
  
  given (360/n)=40, therefore n=(360/40)=9

• measure of interior angle=180-360/n=2.5
  hence nt possible
• 13 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
