Answer:
Troy is 9.4 miles from his starting point.
Step-by-step explanation:
Using the Pythagorean theorem, we can calculate the straight distance from his start to end point, which would be the hypotenuse. 8 miles due east will be the first leg, A, and 5 miles due north will be the second leg, B. A(8) squared plus B(5) squared = C squared. C would equal 9.43, rounded to the nearest tenth is 9.4
