Let A and B be the angles.
\n" ); document.write( "\"A%2BB%2BA%2BB=360\"
\n" ); document.write( "\"A=B-18\"
\n" ); document.write( "Substituting,
\n" ); document.write( "\"B-18%2BB%2BB-18%2BB=360\"
\n" ); document.write( "\"4B-36=360\"
\n" ); document.write( "\"4B=396\"
\n" ); document.write( "\"B=99\"
\n" ); document.write( "So then,
\n" ); document.write( "\"A=99-18\"
\n" ); document.write( "\"A=81\"
\n" ); document.write( "
\n" );
