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

Answer 1

Answer:

11

Step-by-step explanation: let n be the side of the polygon

total angle of the polygon = 5 times the right angle+ 195*(n-5)

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

after solving gives n=11
