35 km
21 km
b
What is the length of the missing leg?
b =
kilometers

Answer 1

28 km

Explanation:

One leg = 35 km

Second leg = 21 km

We need to find the length of the missing leg. Using Pythagoras theorem, we can find it.

Hypotenuse² = base² + perpendicular²

`x=\sqrt{35^(2)-21^(2)}\\\\x=28\ km`

So, the length of the missing leg is equal to 28 km.
