    Post Sin,Cos,Tan

    let's say a=10

    and the adjacent theta(degrees) = 60
    and the opposite theta(degrees) = 30

    without doubt there's an orthagonal angle(90degrees)

    can you tell me what is b, and c?

    This question was obviously weird to me, once upon a time a boy came to me and ask me.

    b/a = adj/opp = tan 60° so.... b = a*tan(60°)

    and

    a/c = opp/hyp = sin 30° so.... c = a/(sin(30°))

    yes, sorry, the answer is correct but i made a typo there

    b still equals a*tan(60°)
