Lets assume the force is along the x axis. Lets assume the 51lb force is also along the x axis.
\n" ); document.write( "What angle is the 45lb force at wrt to the x axis such that the total force along x is 73?\r
\n" ); document.write( "\n" ); document.write( " $\"73+=+51+%2B+45%28cos%28x%29%29\"$
\n" ); document.write( " $\"%2873+-+51%29%2F+45+=+cos%28x%29\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"0.489+=+cos%28x%29\"$
\n" ); document.write( " $\"arccos%280.0489%29+=+x\"$
\n" ); document.write( "60.7 degrees =x \n" ); document.write( "

\n" );
