Finding vector components

    3. The attempt at a solution

    I don't know how to approach this simple problem. I don't know what role A+B+C = -1.90i plays. Even if the vector of B is found, I don't understand how to find the components of B.

    Clearly you can see that the resultant of A+B+C gives something i right? That means the sum of the j components=0.

    Can you split B in to i and j components and use what I said before?

    I got it, thanks. I was confused because I didn't know that i and j corresponded to x and y.
