Answer:
B&D
Step-by-step explanation:
i think this is correct, if not let me know, correct me.
The sinusoid makes a complete oscillation (i.e. 360°) every 3 seconds. So, in one second it makes 1/3 of a turn, leading to 360°/3 = 120°.
So, the correct answer is the last one.
1/3+3/4=4/12+9/12=13/12=1 and 1/12. (1 1/12)
5/6+2/3=5/6+4/6=9/6=3/2 or 1.5 or 1 and 1/2.
