\n" ); document.write( "Subtract second equation from first,
\n" ); document.write( " $\"A%2BS-A-C=180-90\"$
\n" ); document.write( " $\"S-C=90\"$
\n" ); document.write( "Also,
\n" ); document.write( " $\"S=4%2B2C\"$
\n" ); document.write( "Substitute,
\n" ); document.write( " $\"%284%2B2C%29-C=90\"$
\n" ); document.write( " $\"4%2BC=90\"$
\n" ); document.write( " $\"C=86\"$ degrees
