NEED HELP NOW 0<= theta <= 360 theta=30 (degrees) Find two other possible values (so coterminal) so i got 150 but i'm also getting 240 which is wrong it's 270 but i don't get why

Well from my understanding of "coterminal" 150°, 240°, and 270° are all wrong. Coterminal angels are angels positions in the same quadrant which in this case would be Quadrant 1. So coterminal angels would be -330° or 390° See picture for a better representation.
