So basically the x will want to be singled out and 3/2-y=the variable
your answer would be -2.57142857143
For letter the answer is 2
for letter b the answer is 1
sin(x) = opp/hyp
cos(x) = adj/hyp
tan(x) = opp/adj
sin(x) = 3.9/8.1
sin(x) = 0.481
Inverse sin of 0.481 = 28.8 degrees
Each answer should be between 0 and 90 :)
