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( " |
