a regular triangle is an equilateral triangle, then
\n" ); document.write( "AB = BC = AC
\n" ); document.write( "therefore
\n" ); document.write( "7y + 12 = 9y + 4
\n" ); document.write( "2y = 8
\n" ); document.write( "y = 4
\n" ); document.write( "AC = 40
\n" ); document.write( "BC = 40
\n" ); document.write( "AB = 40
\n" ); document.write( "The value of y is 4
\n" ); document.write( "
\n" ); document.write( "
\n" );
