(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 = (n−2)×180∘n
So,(n−2)×180∘n=22∘⇒ 80n−(2×180)=22n⇒ 180n−360=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∘.
