Answer:

3 < x < 13

Step-by-step explanation:

Triangle Inequality Theorem

The sum of the lengths of any two sides of a triangle is greater than the length of the third side.

Let x be the length of the unknown side.

Therefore, x will either be the longest side or one of the shorter sides.

Therefore:

   x < 5 + 8

⇒ x < 13

And:

   8 < 5 + x

⇒ 3 < x

So the range of possible values of the third side is greater than 3 and less than 13:   3 < x < 13
