Answer:
540 degrees
Step-by-step explanation:
The cosine of an angle on a unit circle yields the x value. Therefore, wherever the x value is -1, cos O is -1. Cosine is equal to -1 at 180 degrees, and every 360 degree interval after that. Since 180 degrees is not an option, we need to try the next interval of 360. 180+360=540 degrees, which is one of the options. Hope this helps!

Answers: A, C, and F</h3>
All of these equations are in the form Ax+By = C
- An equation like x+y = -1 has A = 1, B = 1, C = -1
- An equation like x+4y = 0 has A = 1, B = 4, C = 0
- An equation like 8x-3y = 20 has A = 8, B = -3, C = 20
