A bicycle wheel has spokes that go from a center point in the hub to e...
To find the smallest possible angle between any two spokes, we need to determine the maximum number of spokes on the wheel.
For a bicycle wheel, the number of spokes is typically even and can be 2, 4, 6, 8, and so on. However, the question states that there are fewer than six spokes. Therefore, the possible numbers of spokes are 2, 4, or 5.
For 2 spokes, the angle between them is 180 degrees.
For 4 spokes, the angle between any two adjacent spokes is 360 degrees divided by 4, which is 90 degrees.
For 5 spokes, the angle between any two adjacent spokes is 360 degrees divided by 5, which is 72 degrees.
Since we want to find the smallest possible angle, we choose the smallest value among the options, which is 72 degrees.
Therefore, the smallest possible angle between any two spokes is 72 degrees. Hence, the answer is E.
