Question

Sum of the interior angles of a polygon is 5 times the sum of its exterior angle. Find the number of sides
of the polygon.

Answer 1

Answer:

12 sides

Step-by-step explanation:

Sum interior angles = (n-2)×180

= (12-2)×180

= 10×180

= 1800

Sum of exterior angles = 360 (all the polygons have sum of exterior angles as 360)

360 × 5 = 1800
