You can put this solution on YOUR website!
supplement angles add up to 180
\n" ); document.write( "A+B=180
\n" ); document.write( "A=2B-21 \"A is 21 less than twice as large as its supplement angle B\"
\n" ); document.write( "

\n" ); document.write( "i dont know if ur looking for just the expression or trying to solve for each angle?
\n" ); document.write( "

\n" ); document.write( " $\"%282B-21%29%2BB=180\"$
\n" ); document.write( " $\"3B=201\"$
\n" ); document.write( " $\"B=67\"$
\n" ); document.write( "

\n" ); document.write( " $\"A=2B-21\"$
\n" ); document.write( " $\"A=2%2867%29-21\"$
\n" ); document.write( " $\"A=134-21\"$
\n" ); document.write( " $\"A=113\"$
\n" ); document.write( "

\n" ); document.write( "Check
\n" ); document.write( " $\"A%2BB=180\"$
\n" ); document.write( " $\"113%2B67=180\"$
\n" ); document.write( " $\"180=180\"$
\n" ); document.write( "Correct\r
