The formula for sine is a/SinA = b/SinB = c/SinC. Therefore why in the second question are the sin values on the top of the fraction when they were the denominator in the first question. Thank you.

is it a must that you mention the two possible angles or can you just mention one of them

i did 72/sin(29) = 113/sin(b), and then 72/113sin(29) and got 1.34264641. I want to know if I did something wrong with the fraction somewhere as I got a different answer when inverting the fraction.
