PLEASE HELP 1) Which of the following equations could be solved to determine the measure of ∠S? IMAGE #1 BELOW!!!
a) sin S / 13 = sin 50.1 / 12
b) sin S / 13 = sin 50.1 / 15
c) sin S / 15 = sin 50.1 / 12

2) Which of the following equations could be solved to determine the length of RS? IMAGE #2 BELOW!!!
a) sin 80 / RS = sin 52.2 / 7
b) cos 52.2 / RS = cos 52.2 / 7
c) sin 52.2 / RS = sin 80 / 7
