You can put this solution on YOUR website!
If angle A is A
\n" ); document.write( "angle B is 4A
\n" ); document.write( "angle C is 5A - 9
\n" ); document.write( "Total is 180
\n" ); document.write( "So A + 4A + 5A - 9 = 10A - 9 = 180
\n" ); document.write( "10A = 189
\n" ); document.write( "A = 18.9
\n" ); document.write( "B = 75.6
\n" ); document.write( "C = 85.5
\n" ); document.write( "Total = 180
\n" ); document.write( "
\n" );
