It would be best to keep it the same. So if I knew the hypotenuse was 9 and that one side was 4 and I was looking for the other one I would right it like this:
4^2 + B^2 = 9^2 Then simplify 16 + B^2 =81 Then subtract B^2 = 65 And then take the square root of both sides <span>B = 8.0622577483 (since I came up with random numbers it ended up so uneven :P)
Does that make sense to you? I hope that helped you to understand! Feel free to let me know if you have any questions!
