Question
Hi I have a math question i am not sure how to do:
Which of the following angles are coterminal with 80?
800, -100, -280, 280
Can you please explain coterminal to me? thank you!
Put the angles on a graph and you will see that 800 =
2(360) +80.
80 degrees and 800 degrees are the same angle which you could see if you knew how to draw angles on a graph. I've answered over 1000 questions on this web site and have a rating about 9.5 so your feedback means little.

| Comment | I was not given a clear explanation of what to do, or how to even attempt the question. A graph will not help because I just get a whole bunch of lines, not an equation. | ||
