I think you need to say what A and B are before we can decide whether they're needed or not. As it is, you don't know whether the 5 is the hypotenuse or one of the shorter sides. Either way you can have infinite right angled triangles.
As a counter example to the other postings referring to 3-4-5 triangles, what of e.g. 5-12-13, or root12-root13-5 triangles. As it stands, those too fit your question

Well, keep in mind the pythagorean theorem, if one side of the right triangle is 5 cm, and we need to find the 3rd side then you can say A^2+5^2=B^2....therefore the third side would equal A+5=B, if B was the third side. Also, if even one side is 5 then you can assume that in a right triangle a common set lengths that are repeated commonly are a 3,4,5 right angle...this means one side is 5cm, one side is 4cm, and the last side is 3cm. If you use the pythagorean theorem it should add up.

In a right angle triangle if one side is 5 units then the others have to be 3 and 4 units respectively.
