Step-by-step explanation
Since the kite is flying 8 ft from the ground, we can apply the Pythagorean Theorem to obtain the value of the line, by assuming that x represents the unknown value, as shown as follows:

Computing the powers:

Adding numbers:

Applying the square root to both sides:
![x=\sqrt[]{113}=10.63014581](https://img.qammunity.org/2023/formulas/mathematics/college/w8tdc3e43v6fsc4330ttkbgmgt4yv5b3qd.png)
Rounding to the nearest tenth:

In conclusion, the unknown distance is 10.6 ft
