Answer:
<em>1. B.</em>
<em>2. B.</em>
Step-by-step explanation:
<u>Trigonometry</u>
1) Coterminal angles can be found by adding or subtracting 360° (or 2\pi radians) to a given angle. If we have 120°, adding 360° gives 480°, adding again 360° gives 840°. There is no way to get -180°, so this option is not a coterminal angle to 120°
2)
A. , and not undefined
B. . This is correct
C. is undefined, not zero
Thus the only correct option is B.
