Question

The sum of the interior angles of a regular polygon is twice the sum of its exterior angles. Find the number of sides of the polygon.​

Answer 1

Answer:

Int.angle=2 extrangle

extrangle=x

intr. angle-2x

x+2x=l80

3x =l 80

x=60 degree

Extr. angle x=60

No:of sides = 360/Extrangle

= 360/6=6

Answer 2
