Question

What is the number of the sides of a polygon whose ratio between the exterior and the interior angles is 1:4?
It's a regular polygon

Answer 1

exterior angle : interior angle = 1:4

exterior angle = 180

1===180

4==180*4= 720

Interior angle== (n-2)*180 = 720

n-2 = 720/180 = 4

n = 4+2 =6 sides
