Answer:
[tex]\sqrt{89}[/tex] km
If we use the Pythagorean Theorem for this problem, we will arrive with an answer of [tex]\sqrt{89}[/tex].
Formula: [tex]a^{2} + b^{2} = c^{2}[/tex]
Solution: [tex]5^{2} + 8^{2} = c^{2}[/tex], then it will become 25 + 64 = c^2.
so c is equal to the square-root of 89.
