Find the measure of an angle between 0o and 360o coterminal with an angle of - 271o in standard position.

181o

91o

89o

271o

The correct answer is: 89°

Explanation:

As the angle - 271° has the negative sign, it means we have to add 360° to it in order to find the coterminal angle (and the answer should be between 0° and 360°).

Hence, - 271° + 360° = 89°

Note (bonus information) : If the angle were positive, you would have to subtract 360° from it to find the coterminal angle.
