    to solve this you can graph the function and see how long it takes to repeat itself. However since you are looking for an answer in degrees and not radians you will need to graph the following y=2*sin(3x*(pi/180))

    pi/180 is the conversion factor from radians to degrees.

    the graph is attached and the answer is 120 degrees.
