Question

Is an angle in the unit circle that terminates on the x-axis. Which of the following options does not represent a possible measure for ?

1) 540°
2) -5π
3) 5/2π
4) -360°

Answer 1

An angle in the unit circle that terminates on the x-axis can have a measure of 0° or 180°.

Step-by-step explanation:

An angle in the unit circle that terminates on the x-axis is either 0° or 180° (or 0 or π radians). Therefore, the option that does not represent a possible measure for this angle is 540° (or 3π radians) which is beyond a full revolution.
