In this study, we present the first radial velocity measurements of the eclipsing binary BD+72 780. We simultaneously modeled TESS light curves with our radial velocity data to derive the orbital and absolute parameters of the system. The analysis shows that the system is a detached binary with two different spectral types of components, and the orbit is slightly eccentric (e ∼ 0.07).
