Since angles ABC and BCA are equal then sides AC and AB are equal
\n" ); document.write( "(3x - 5)=(19 - x)
\n" ); document.write( "4x=24
\n" ); document.write( "x=6
\n" ); document.write( "18-5=13 AB
\n" ); document.write( "19-6=13 AC
\n" ); document.write( "2*6=12 BC
\n" ); document.write( "13+13+12=38 cm
\n" ); document.write( "
\n" );
