Just look at it. You can always immediately look at a triangle and tell whether or not you can use the Law of Sines. You need either 2 sides and the non-included angle (like this triangle) or 2 angles and the non-included side. Remember, the law of sines is all about opposite pairs. The law of sines always “works” when you have all acute angles. It’s only when the angle in question is an obtuse angle that we have a problem. (and, as @GMichaelGuy pointed out, it always works, it just makes us do a little more work.) Notice I used the arcsine. Turns out, the arcsine isn’t a function. Which means when you “undo ...
