Answer:
8 miles
Step-by-step explanation:
You can think of it as a triangle, which will look like the picture at the bottom.
You're trying to find the missing length, and to do that you can use the Pythagorean theorem.
That would be:
[tex]6^{2} + x^{2} =10^{2}[/tex]
Then, solving:
[tex]36 + x^{2} =100\\x^{2} = 64\\x = 8[/tex]
Therefore, the answer is 8 miles
