Internal Forces $-$ Deformable Body Equilibrium

The following system is pinned at A and has a cable $BD$ attached to the beam at point $B.$ The system is point loaded at $C.$ Hint #$1$: The vertical reaction at pin $A$ is $22\mathrm{.}5$kNdarr. Hint #$2$: You must calculate the horizontal reaction at pin A$.$ This involves the force in cable BD$.$
