We analyze the joint decays of [ital C]=[plus minus]1 [ital B][sub [ital d]][sup 0][ital [bar B]] [sub [ital d]][sup 0] pairs at a symmetric [ital B] factory. A few time-integrated measurements of decay rates and [ital CP]-violating asymmetries are proposed for [ital B][sub [ital d]][sup 0],[ital [bar B]] [sub [ital d]][sup 0][r arrow][pi][sup +][pi][sup [minus]],[pi][sup 0][pi][sup 0],[psi][ital K][sub [ital S]] and [ital B][sub [ital u]][sup [plus minus]][r arrow][pi][sup [plus minus]][pi][sup 0] both on the [Upsilon](4[ital S]) resonance and just above it. We show that it is possible to extract three angles of the Cabibbo-Kobayashi-Maskawa unitarity triangle from such measurements unambiguously, even in the presence of significant final-state strong interactions and in the absence of exclusive [ital B][sub [ital s]][sup 0] versus [ital [bar B]] [sub [ital s]][sup 0] decay modes.
