Can anyone solve this and show your work plz

The law of sines states stat the ratio of the sin of an angle to the side opposite of the points is equal for all angles/points/sides

so lets see what the 3 ratios are:
sin(R=100)/3.5
sin(S=?)/2.4
sin(Q=?)/?

so the first option is correct with
sin(100)/3.5=sin(S)/2.4
