Question

If the difference between the exterior angle and interior angle of a polygon is 60°,then find the number of sides of the polygon

Answer 1

Answer:

No. of sides = 3

Step-by-step explanation:

Let no. of sides as n.

Interior angle = (n-2)180/n=180n-360/n

Exterior angle =360/n.

So, 360/n - 180n-360/n =60

=>. n= 3.
