(n - 2) * 180 degrees = 60 degrees
Solving for n:
(n - 2) * 180 degrees = 60 degrees
(n - 2) = 60 degrees / 180 degrees
(n - 2) = 1/3
n = 1/3 + 2
n = 1/3 + 6/3
n = 7/3
Since n must be a whole number representing the number of sides in a polygon, we round up:
n ≈ 3
So, Polygon A has n = 3 sides, making it a triangle.
