(ii) Can it be an interior angle of a regular polygon? Why?

Solution

(i) Since, the sum of all the exterior angles of a regular polygon = 360°, which is not divisible by 22°.
It is not possible for a regular polygon to have its exterior angle as 22°.

(ii) Sum of all interior angles of a regular polygon = (n-2) ×180
Measure of its each angle = (n2)×180n
So,(n2)×180n=22 80n(2×180)=22n 180n360=22n 158n=360 n=360158=18079
Here, n is not a whole number.
Since, the number of sides cannot be in fractions,
It is not possible for a regular polygon to have its interior angle = 22.
