The three different helicity states of W(+/-) bosons, produced in the reaction e(+)e(-) --> W(+)W(-) --> lvq (q) over bar are studied using leptonic and hadronic W decays at root s = 183 GeV and 189 GeV. The W polarisation is also measured as a function of the scattering angle between the W(-) and the direction of the e(-) beam. The analysis demonstrates that W bosons are produced with all three helicities, the longitudinal and the two transverse states. Combining the results from the two center-of-mass energies and with leptonic and hadronic W decays, the fraction of longitudinally polarised W(+/-) bosons is measured to be 0.261 +/- 0.016(syst.) +/- 0.016(syst.) in agreement with the expectation from the Standard Model.
