Question

Calculate the number of sides of a regular polygon, if the exterior angle exceeds its interior angle by 60°

Answer 1

Step-by-step explanation:

let the interior angle be x

thus , exterior angle = x+60

x+x+60=180. ...adjacent angles

x=60

exterior angle =120°

as we know that sum of all the exterior angles of any polygon is 360

so ,360÷120=3

no of sides =3

Answer 2

Answer:

3

Step-by-step explanation:

its a triangle since the outer angle exceeds by 60..so x plus 60 plus x is 180

x=60
