Algebra 2 question..... Needed the opposite, if it was would be 150 but if it isn't ?.

Answer:
120°
Step-by-step explanation:
180 + 30 = 210
30 - 360 = -330
0 - 30 = -30
120 does not have a basic angle of 30, it's basic angle is 60°
Because,
180 - 120 = 60
Answer:
120
Step-by-step explanation:
A reference angle is the angle it makes with the x axis,
120 makes a 60 degree angle with the x axis
(180-120) = 60 It is closer to the negative x axis
210 is closer to the negative x axis which is 180
210-180 = 30
-330 is closer to the positive x axis which is 0 or 360
-330 - (-360) = 30
-30 is closer to the positive x axis which is 0
-30 - (0) = -30
-30 but the angle itself is 30
