  2. You MUST know the trig ratios of a right-angled triangle for the base angle in terms
    of its adjacent, opposite and hypotenuse side
    sinØ = opposite/hypotenuse or y/r
    cosØ = adjacent/hypotenus or x/r
    tanØ = opposite/adjacent or y/x
    perhaps in your class you have learned: SOH CAH TOA

    so for your question, I notice you are dealing with opposite = 31.9
    and adjacent = 55

    go for it

  3. Tan =opp/adj
    55/3.19
    =17.241 degrees
