Incorrect. Note that $\displaystyle\angle{C}{F}{D}\usepackage{cmbright}\Huge\$ is a right angle, so it measures $\displaystyle{{90}}^{\circ}\usepackage{cmbright}\Huge\$ . Also note that $\displaystyle\angle{A}{F}{D}\usepackage{cmbright}\Huge\$ and $\displaystyle\angle{B}{F}{E}\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.
