If the sum of the measures of all the interior angles of polygon is 2340°. What is the number of sides of the polygon?
Let number of sides of the polygon = $$n$$
Sum of all interior angles of a polygon having $$n$$ sides = $$(n - 2) \times 180$$° = $$2340$$°
=> $$(n - 2) = \frac{2340}{180} = 13$$
=> $$n = 13 + 2 = 15$$
$$\therefore$$ The polygon having sum of interior angles 2340° has 15 sides
=> Ans - (B)
