Question

Find The Number Of Sides Of A Polygon Whose Sum Of Interior Angle Is
1- 28 Right Angle
2- 38 Right Angles
3- 1440°​

Answer 1

Answer:

Given-  sum of interior angles = 16 right angles= 16*90=1440

As we know

Sum of interior angles of any polygon = (2n - 4)*90

=> (2n - 4)*90= 16*90 (given)

=> 2n-4 =16

=> 2n= 20

Hence, n= 10

Total  number of sides in a polygon =10
