Incorrect. Draw the angle in standard position: it has its initial side on the x-axis and moves counter-clockwise to the terminal side. The terminal side is in the fourth quadrant, because the angle measure is between $\displaystyle{{270}}^{\circ}\usepackage{cmbright}\Huge\$ (the negative y-axis) and $\displaystyle{{360}}^{\circ}\usepackage{cmbright}\Huge\$ (the positive x-axis). Now find the measure of the angle formed by the terminal side and the positive x-axis. This is the reference angle. The correct answer is $\displaystyle{{10}}^{\circ}\usepackage{cmbright}\Huge\$ .
