Answer 1

Answer:

8 sides.

Step-by-step explanation:

The exterior angle of regular polygon is 1/3 of its interior angle. find the number of side of polygon ?? Ans -8 sides.

Answer 2

Answer:

Let the measure of interior angle of the polygon be x then its exterior will be x / 3

But since they form a linear pair

4x / 3 = 180; x = 135 degrees; x + x / 3 = 180 Now let the no. of sides of polygon be n So, 180(n - 2) = 135n; 80n - 360 = 135n; 45n = 360; n = 8 So no. of sides of polygon are 8 i.e.polygon is an octagon.PLEASE MARK AS BRAINLIEST:)
