Question

A right triangle has side lengths of 4 unit's, 5 unit's and x units. It is unkown If the missing length is the longest or shortest side round to the nearest 10th what is the difference between possible x values

Answer 1

If x is the hypotenuse then
hyp^2 = 4^2 + 5^2
hyp^2 = 41
hypotenuse = 6.403124


if x is a leg then
leg^2 = 5^2 - 4^2
leg^2 = 25 - 16
leg^2 = 9
leg =3
