We measure the bulk system parameters of the seismically active,rapidly-rotating $\delta$-Scuti KOI-976 and constrain the orbit geometry of itstransiting binary companion using a combined approach of asteroseismology andgravity-darkening light curve analysis. KOI-976 is a$1.62\pm0.2~\mathrm{M_\odot}$ star with a measured $v\sin(i)$ of $120\pm2$ km/sand seismically-induced variable signal that varies by $\sim$ 0.6\% of thestar's total photometric brightness. We take advantage of the star's oblateshape and seismic activity to perform three measurements of its obliquity anglerelative to the plane of the sky. We first apply rotational splitting theory tothe star's variable signal observed in short-cadence \emph{Kepler} photometryto constrain KOI-976's obliquity angle, and then subtract off variability fromthat dataset using the linear algorithm for significance reduction software{\tt LASR}. We perform gravity-darkened fits to \emph{Kepler}variability-subtracted short-cadence photometry and to \emph{Kepler's}phase-folded long-cadence photometry to obtain two more measurements of thestar's obliquity. We find that the binary system transits in a grazingconfiguration with measured obliquity values of $36^\circ\pm17^\circ$,$46^\circ\pm16^\circ$, and $43^\circ\pm20^\circ$ respectively for the threemeasurements. We perform these analyses as a way to demonstrate overcoming thechallenges high-mass stars can present to transit light curve fitting and toprepare for the large number of exoplanets \emph{TESS} will discover orbitingA/F stars.
