    30.a correct
    30.b you found both negative, and you need one positive and one negative
    here are positive:
    Positive coterminal angles: 300°, 660°, 1020°, 1380°, 1740°...

    At least I got 30 (a) right.

    Note 1: Occasionally, I like to search through my textbooks for interesting questions. I found quite a few problems for which I would like to see your work from start to finish. Look in the Algebra forum.

    Note: After tonight, we will take a small break from precalculus for a few days. I need to give you some breathing room. I also need a mental break from mathematics.
