Answer:The answer to your question is b = 148.5Step-by-step explanation:To solve this problem, use trigonometric functionstan Ф = [tex]\frac{opposite side}{adjacent side}[/tex]opposite side = badjacent side = 60tan Ф = tan 68° = 2.48Opposite side = adjacent side x tan ФOpposite side = 60 x 2.48Opposite side = b = 148.5
