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°))

i thought to get tan(), you must opp/adj:)

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

b still equals a*tan(60°)
