You can put this solution on YOUR website!
suplementery angles are angles whos total add to 180 degrees
\n" ); document.write( "the problem would be
\n" ); document.write( " $\"n=4m-5\"$
\n" ); document.write( "and $\"n%2Bm=180\"$
\n" ); document.write( "so for 4m-5 plug in n
\n" ); document.write( " $\"4m-5%2Bm=180\"$
\n" ); document.write( "then combine like terms
\n" ); document.write( " $\"5m-5=180\"$
\n" ); document.write( "add 5 to moth sides
\n" ); document.write( " $\"5m=185\"$
\n" ); document.write( "divide both sides by 5
\n" ); document.write( " $\"m=37\"$
\n" ); document.write( "then plug 37 in for m
\n" ); document.write( " $\"n%2B37=180\"$
\n" ); document.write( "subtract from both sides
\n" ); document.write( " $\"n=143\"$
\n" ); document.write( "i hope that helps
