Abstract: CCD photometric observations of the Algol-type eclipsing binary X Tri havebeen obtained. The light curves are analyzed with the Wilson-Devinney WD codeand new geometric and photometric elements are derived. A new O-C analysis ofthe system, based on the most reliable timings of minima found in theliterature, is presented and apparent period changes are discussed with respectto possible and multiple Light-Time Effect LITE in the system. Moreover, theresults for the existence of additional bodies around the eclipsing pair,derived from the period study, are compared with those for extra luminosity,derived from the light curve analysis.
