Solving triangle

[Ashleymcarton7]

Hello. I have a right triangle I need to solve for all angles and side lengths.

side A is 34.21 cm, Side B is unknown and Side C (hypotenuse) is unknown.

side a is the height side b is the base

the right angle is between side a and b

Is this a real-world problem? You need three bits of information before you can work out the rest of the triangle. At the moment you only have two ("right angle" and "length of A"). Therefore you need another side, or another angle!

EDIT: Perhaps if you explain more about the context of the problem then we might be able to help you. As it stands, there is nothing to stop side B getting longer or shorter.
