Identify all coterminal angles between -360 degrees and 360 degrees for the angle -420 degrees.
first I divided -420 by 360 which gave me -1.166666667. Then I added 1 to that which left me -.166666667. I multiplied that by 360 which left -60. I then subtracted 60 from 360. Which left 300 degrees. Is this all I have to do and is it correct.
