Answer:
Step-by-step explanation:
We are given PS = 28 feet, which is the length of the diameter.
The formula for arc length is , where x is the degrees.
So, we need to find the radius. We know that the radius is half of the diameter, so:
We also need to find ∠TXS. Since we know the diameter is a line that crosses the center point of the circle, we also know that ∠PXT and ∠TXS add up to 180°. So:
∠PXT + ∠TXS = 180
125 + ∠TXS = 180
∠TXS = 180 - 125
∠TXS = 55°
Now, we can use the arc length formula:
