it appears trig functions will only work with degrees necessitating converting DMS into decimal form, but it appears trig functions will not take the results of another function either ie "FromDMS" and gives erroneous answers which is baffling or I am doing something wrong, which is quite possible. I got the right answer in a two step prossess, but I would think you could do it in just one.

Sin[FromDMS[{49,12,0}]]//N
FromDMS[{49,12,0}]//N
Sin[49.2\[Degree]]
Sin[49.2\[Degree]]==Sin[FromDMS[{49,12,0}]]
Sin["49\[Degree]12'0\""]//N
ArcSin[-0.8750225789894467`]180/\[Pi]
ArcSin[0.7569950556517565`]180/\[Pi]
Sin[DMSString["49\[Degree]12'0\""]]
Sin[DMSString[{49,12,0}]]
