a^2=b^2+c^2-2bc cos A
\n" ); document.write( "=64+25-2(40) *0.3746=89-29.97=59.03
\n" ); document.write( "sqrt(59.03)=7.68
\n" ); document.write( "Now use law sines
\n" ); document.write( "sin 68/7.68=sinC/5
\n" ); document.write( "sin C=.6034
\n" ); document.write( "Take arc sin both sides: C=37.11
\n" ); document.write( "I will choose D. \n" ); document.write( "
