Question

If a triangle has side lengths of 5.6 yards, 7.1 yards, and `x` yards, what are possible values of `x`?

Answer 1

`1.5<x<12.7`

Explanation:

All triangles have the third side lower than the sum of the remaining sides and greater than their difference.
Then it is:

`x<5.6+7.1` and `x>7.1-5.6`

that's

`1.5<x<12.7`
