Abstract We consider within the standard model the time-dependent decay rates of the three processes B d 0 → D 0 K s , D 0 K s and D 1 0 K s , where D10 is a neutral D meson CP-eigenstate. We show that it is possible to derive from these processes, in which two weak amplitudes are involved, two of the three angles in the unitarity triangle of the Cabibbo-Kobayashi-Maskawa matrix. The third angle can be determined from Bs0 → Dφ. All three angles are obtained free of hadronic final-state uncertainties.
