Let the angle = x
\n" ); document.write( "x measures 120 less than 180-x
\n" ); document.write( "\"x=180-x-120\"
\n" ); document.write( "Subtract
\n" ); document.write( "\"x=60-x\"
\n" ); document.write( "Add x to both sides
\n" ); document.write( "\"2x=60\"
\n" ); document.write( "Divide both sides by 2
\n" ); document.write( "\"x=30\"
\n" ); document.write( "
\n" );
