Q24.The interior angles of a polygon with n sides, are in an A.P. with common difference 6∘ . If the largest interior angle of the polygon is 219∘ , then n is equal to . Then limx→0 (x−f(x))ex−ef(x) is equal to
What This Question Tests
This question combines the concept of arithmetic progression with the geometric properties of polygons to find the number of sides of the polygon given its angle characteristics.
Concepts Tested
Formulas Used
Sum of angles of n-sided polygon = (n-2) * 180°
S_n = n/2 * (2a + (n-1)d)
