Question

an n-sided regular polygon, each exterior angle
is 72º. Find the sum of all the interior angles of the
polygon​

Answer 1

Step-by-step explanation:

Sum of extetior angles of a polygon = 360°

given each exterior angle = 72°

360/72 = 5

n = 5

we can say that polygon is a pentagon

sum of interior angles of a pentagon = (n -2)180

= (5 - 2 ) 180

= 3 (180)

= 540
