Pre Calculus trigonometry

Question

Is the coterminal angle θ for 1399 degrees 319 degrees? (-319 for -360 degrees<θ<0 degrees)

and is reference angle 41 degrees?

Answer 1

360(4) = 1440

1440 - 1399 = 41 degrees = reference angle = the coterminal angle too in quadrant I

for a coterminal angle of 319 degrees the angle would have had to have been 1399-41 = 1358 =-41 degrees
