Question

A right triangle has side lengths 4 units, 5 units, and x units. It is unknown if the missing length is the longest or shortest side. Rounded to the nearest tenth, what is the difference between the possible values of x?

Answer 1

3.4 units

Explanation:

Answer 2

If it is the longest side then:
5^2+4^2=x^2
Where x= sqrt41

If it is the shortest side then:
4^2+x^2=5^2
Where x=3

Sqrt41-3= 3.4
