Question

Find the number of sides of a rectangular polygon if each of its interior angle is 1650​

Answer 1

Answer: The formula used in this question is

                (n-2) x 180° = Sum of all int. angles          (n is no. of sides)

                180°n - 360° = 165° x n

                180°n - 165°n = 360°

                15°n = 360°

                     n = 360°/15°

                     n = 24
