Question

Which angle is coterminal with 140°? A. 500° B. 320° C. -140° D. 490° SUBMIT

Answer 1

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.

`\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}`

Answer: Positive co-terminal angle of 140 degree is 500 degree.

Option A is correct.
