Question

In a polygon there are 5 right angles and the remaining angles =195degrees each .Find number of sides.?

Answer 1

let the number of sides of the polygon be n.

therefore the sum of the interior angles of a polygon with sides n is (n-2)* 180.

it is given that there are 5 right angles and remaining angles are equal to 195.

therefore sum of interior angles = 5*90+(n-5)*195

hence,the above given picture is the solution



thus the polygon has 11 sides.
