A model-independent method based on the triangle ideology is implemented to extract the CKM-matrix angle gamma in the decays of the doubly heavy long-lived meson B-c. We analyse a colour structure of diagrams and conditions to reconstruct two reference triangles by tagging the flavour and CP eigenstates of D-0 <----> (D) over bar (0) mesons in the fixed exclusive channels. The characteristic branching ratios are evaluated in the framework of QCD sum rules.
