Answer:
12
Explanation:
The sum of the exterior angles of a polygon = 360°
Since there are n sides and each exterior angle =
, then
n ×
= 360 ( multiply both sides by 2 to clear the fraction )
5n² = 720 ( divide both sides by 5 )
n² = 144 ( take the square root of both sides )
n =
= 12
The polygon has 12 sides
