Adding Vectors

  1. Aug 30, 2015 #1
    1. The problem statement, all variables and given/known data
    Express the vector R in terms of A, B, C, D
    (VIEW IMAGE ATTACHED)

    2. Relevant equations


    3. The attempt at a solution
    R=B-D
    OR
    R=A+C

    In this problem, I figured that because of the way the arrows are pointing R+D=B which you can then simplify to R=B-D. However, this is not an answer to the problem.

    I then tried using the other triangle with R. Because of the way the arrows are pointing, I figured that A+C=R. However, this is also not a solution to the problem.

    Right. And one of those works just fine.
