The nonspectator contributions to the B-meson decays are calculated with use of the measured ratio tau/sub D//sup +//tau0 and the assumption f/sub B//sup 2//f/sub D//sup 2/ = m/sub D//m/sub B/. We find tau/sub B//sup +//tau0 = 1.4 to 1.8. From the measured values of B-meson lifetime, the semileptonic branching ratio, the ratio GAMMA(b..-->..ue..nu..)/ GAMMA(b..-->..ce..nu..), and the epsilon parameter, the constraints on Kobayashi-Maskawa angles are evaluated and their implications for m/sub t/, Vertical Barepsilon'/epsilonVertical Bar, B/sup 0/-B-bar /sup 0/ mixing, and K..--> pi nu..nu-bar are presented.
