Question
Given the following vectors, where Vector A is 6.3 meters and Vector B is 3.5 meters, determine the magnitude of the following vector sums: A+B, A-B, B-A
I tried to do magnitude such as A+B = square root (6.3)^2+(3.5)^2 = 7.2 then A-B = square root (6.3)^2-(3.5)^2 = 5.2 then got unreal answers on B-A when square root (3.5)^2-(6.3)^2 was put into the calc.
If vector component Vh is -8.50 units and Vv is 4.80 units, what is the magnitude and direction of Vector V?

just given arbitrary vectors of some magnitudes, there is no way to compute their sum or difference.
Unless you know the x- and y-components, you are stuck.

No way to solve?
