Correct. The angle in standard position has its initial side on the x-axis and moves counter-clockwise to the terminal side, shown in the second quadrant. It measures $\displaystyle{{40}}^{\circ}\usepackage{cmbright}\Huge\$ less than a straight angle. So its measure is $\displaystyle{{180}}^{\circ}-{{40}}^{\circ}={{140}}^{\circ}\usepackage{cmbright}\Huge\$ .
