Hi:

Is what I have circled correct?

I thought sin = opp. / hyp. thus sin*hyp. = opp. or in that picture's case sin*d = opposite, but the sin*d term is listed as the adjacent...

Thanks in advance.

 

The illustration is correct as shown.

You have to look at the triangle with respect to that angle theta drawn, not the other triangle I was looking at... got it.
