Please help! I was asked to determine the two coterminal angles (one positive and one negative) for the angle. Giving the answers in degrees.
central angle = 740 degrees
After converting the degrees for both into rads and subtracting and then adding 18PI/ 9 and then multiplying that answer by 180 degrees/ Pi. I received that angles 740 degrees and 380 degrees, but the answer is 20 degrees and -340 degrees. What did I do wrong? :? Thank you for your help! [/list]
