In this study, we present a detailed photometric investigation of three classical Algol-type binaries that contain a 𝛿 Scuti-type pulsating component. The photometric analysis of the selected Algol systems was performed using high-precision data from the Transiting Exoplanet Survey Satellite (TESS), which provides continuous space-based observations. For the EW Boo system, both the radial velocity curves of the components and the TESS light curve were analyzed simultaneously, allowing a reliable determination of its physical parameters. The photometric modeling of the other two systems, WY Cet and SX Dra, was carried out without available radial velocity measurements but still produced consistent solutions. From the analysis, the absolute masses and radii of the stellar components were derived for all systems. Furthermore, their evolutionary status was discussed by comparing their locations on the Hertzsprung–Russell diagram (HRD), highlighting their significance for understanding stellar evolution in interacting binaries with pulsating components.
