Question

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

Answer 1

Answer:

(n-2) *180=5*90+(n-5) *195

180n-360=450+195n-975

15n=165

n=165/15=11

let the number of sides of the polygon be n

therefore the sum of interior angles of a polygon

with sides n is ( n-2*180)

it is given that there are five right angles and

remaining angles are equal to 195

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

hence the solution is on top place

thus the polygon has 11 sides
