Question

In a polygon, there are 5 right angles and the
remaining angles are equal to 195° each. Find
the number of sides in the polygon.​

Answer 1

Let the sides of the polygon be n

Sum of interior angles= (n-2) x 180

(n – 2) x 180 = 5 x 90 + (n – 5) x 195

n = 11

The number of sides in the polygon is 11.
