Answer:
≈ 7.6 miles
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse d is equal to the sum of the squares on the other 2 sides, that is
d² = 3² + 7² = 9 + 49 = 58 ( take the square root of both sides )
d = [tex]\sqrt{58}[/tex] ≈ 7.6 ( to the nearest tenth )
