Answer
The vectors that appear to be equal are $\mathbf{v}$ and $\mathbf{b}$.
Work Step by Step
The equal vectors are the vectors, having the same direction and same magnitude.
In the given figure only $\mathbf{v}$, and $\mathbf{b}$, appear to be of the same length and in the same direction.
Therefore, only $\mathbf{v}$ and $\mathbf{b}$ appear to be equal.
