Incorrect. Note that $\displaystyle\angle{H}{G}{J}\usepackage{cmbright}\Huge\$ and $\displaystyle\angle{I}{G}{K}\usepackage{cmbright}\Huge\$ are straight angles, so they measure $\displaystyle{{180}}^{\circ}\usepackage{cmbright}\Huge\$ . Use these facts and the given angle measurement in the row to determine the measurements of the missing angles.
