sin θ = opp hyp Find Sin A and Sin B sin A = 24 26 = 12 13 and sin B
... Important note: There is a big difference between sec θ and cos-1x. The first one means "1/cos θ". The second one involves finding an angle whose cosine is x. So on your calculator, don't use your cos-1 button to find sec θ. ...
