WebWhen you write and solve the law of sines, you end up with sinC=0.32 or something. You type sin^-1 (0.32) in your calculator and you are given an acute angle. Actually there are two solutions to the equation sinC=0.32. One is acute (your calculator gave it to you) and the other solution is obtuse.
