We can deduce these algebraic facts from yur statements...
\n" ); document.write( "b + a = 180
\n" ); document.write( "b = 4c
\n" ); document.write( "c + a = 90
\n" ); document.write( "If we substitute 4c for b in the first equation, we get
\n" ); document.write( "4c + a = 180
\n" ); document.write( "c + a = 90
\n" ); document.write( "Now subtract equations and get
\n" ); document.write( "3c = 90
\n" ); document.write( "c = 30
\n" ); document.write( "b = 120
\n" ); document.write( "a = 60
\n" ); document.write( "and all checks out.
\n" ); document.write( "
\n" );
