What is the length of the missing leg? If necessary, round to the nearest tenth. b = _____ kilometers

To find the length of the missing leg (b), we can use the Pythagorean theorem if we are dealing with a right triangle, which states that a² + b² = c², where c is the hypotenuse and a and b are the legs.

If you have the values for one leg and the hypotenuse, plug those numbers into the formula and solve for b.

For example:
1. If a = 3 km and c = 5 km, then:

3² + b² = 5²

9 + b² = 25

b² = 25 – 9

b² = 16

b = √16

b = 4 km

Remember to round your answer to the nearest tenth if needed. If you have specific values for the legs or the hypotenuse, please provide them for a tailored solution!
