Answer:
The answer is 37 km
Step-by-step explanation:
Use the Pythagorean Theorem to solve this question.
a² + b² = c² where c is what you're trying to solve
Plug in your knowns into your equation.
12² + 35² = c²
144 + 1225 = c²
1369 = c²
c = √1369
c = 37

From the attached figure, we conclude that we need to find AC in ∆ABC which is right angled at B.
By the Pythagoras Theorem, we write:
AB² + BC² = AC²
→ 12² + 35² = AC²
→ 144 + 1225 = AC²
→ √1369 = AC
→ AC = 37 km
