Riddle me this MHF.

How come the algebra doesn't provide me with two solutions?

(SinX = SinB and 49 is 49°. This was sketched in a hurry..More like doodled..)

Yes, but the general idea should be obvious. I have two triangles with 2 identical sides and 1 identical corner. That means that I have a different corner B in each triangle but solving with algebra only yields one solution. I am supposed to somehow 'know' to subtract the 2nd solution from 180 to get my 2nd corner and we all know that that's not how mathematics work. There is a reason and I would very much like to know it.

The rest of your answer I do not understand...B and B+450..? - Mar 19th 2013, 07:23 PMShakarriRe: Seemingly flawed algebra

Oops that was silly of me. I tried sketching it and got 105 and 75 :)
