Answer:
Explanation:
The formula to find the interior angle of a polygon is
180(n−2)
n.
(n being the number of sides of the polygon).
Since we know the interior angle of the polygon which is 120, therefore we can produce this equation,
180(n−2) =120
n
From here we use algebra to solve n.
180n−360=120n
60n=360
n=6
∴ Polygon has 6 sides
