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.
