    Hi 02drai :smile:

    Before we deal with D, I'm worried about your answers for C and B …

    C = √(7.072 + 7.072) = √(50 + 50) = 10 …

    yes 10 is correct, but how did you get it? :confused:

    And can you please also say how you got B (yes, it's right too), since if you got it the right way, you should know how to get D.

    What i did was to find resultant from AB was just pythagoras. I have got answer and i tried to put logical equation. However, why i get idea that the resultant should be same for all point since they are all relative to eaxh other.
