Question

the sum of the exterior angles of polygon is one fifth of the sum of its interior angles find number of sides of the polygon don't copy from Google otherwise it will be reported​

Answer 1

Answer:

Explanation: Sum of Exterior angles is always equal to 360°

      Let the sum of the interior angles be x°

Therefore,

      360=1/5x

= x=360 x 5

= x= 1440

We know that sum of interior angles is 2n - 4  x 90

Therefore,

2n - 360=1440

= 2n=1440 +360

= n=1800/2

= n=900

No/of sides is 900
