We combine radial velocity (RV) measurements from TRES/FLWO 1.5 m, and time-series photometry from HATNet, FLWO 1.2 m, BOS 0.8 m and NASA K2 Campaign 5, to determine the masses and radii of the component stars: $M_{A} = 0.448\\pm0.011$ $M_{\\odot}$, $M_{B} = 0.2721^{+0.0041}_{-0.0042}$ $M_{\\odot}$, $R_{A} = 0.4548^{+0.0035}_{-0.0036}$ $R_{\\odot}$, and $R_{B} = 0.2913^{+0.0023}_{-0.0024}$ $R_{\\odot}$.
