When you have angle and its corresponding (opposite) side then you need to use law of  sin. Problems 3,4,5(in 5 you need at first find angle X=180-92-62)


when you have two sides and angle between them, this is law of cos, problem 6,8

problem 7 you can use both, but if you can use both better to use law of sin, it is just easier
