Well, what do you know about Tan, Sin, and Cos?

anonymous · Answer

They're trig functions :D

anonymous · Answer

I'm just confused. How can I figure anything out if I don't have the lengths of a, b, or c..

anonymous · Answer

Sin of B= b/a

anonymous · Answer

Does that make sense @MaryLovell15

anonymous · Answer

Yeah, I understand.

anonymous · Answer

Could someone give me an example of the answer they are looking for. Just so I can see what to do. For tan A.

Sine = $\ \dfrac{Oppo.}{Hypo.} $

Using angle B, |dw:1408932650013:dw|

Therefore $\ \sf Sin B = \dfrac{b}{c} $

Got it?
