Given:
The angle 140 degree.
The co-terminal angles is defined as an angle, where two angle are drawn in the standard position.
It is determine by adding or subtraction 360 degree to each angle.
[tex]\begin{gathered} \text{add 360}^{\circ}\text{ } \\ 360^{\circ}+140^{\circ}=500^{\circ} \\ \text{subtract 360}^{\circ} \\ 140^{\circ}-360^{\circ}=-220^{\circ} \end{gathered}[/tex]Answer: Positive co-terminal angle of 140 degree is 500 degree.
Option A is correct.
