Elements of the Cabibbo-Kobayashi-Maskawa (CKM) matrix are accessible through a variety of processes. The Decay $B^+\!'\rightarrow D_s^+\phi$ is an annihilation diagram at tree level, which is sensitive to $V_{ub}$. While, contributions from the matrix element $V_{ts}$ are present in the loop level decays $B^+\!\rightarrow K^+\pi^+\pi^-\mu^+\mu^-$ and $B^+\!\rightarrow \phi K^+\mu^+\mu^-$. Results from LHCb for all these decays are presented.
