A = 2x
\n" ); document.write( "B = x
\n" ); document.write( "C = x + 2x - 12
\n" ); document.write( "===========================================
\n" ); document.write( "2x + x + x + 2x -12 = 180 degrees.
\n" ); document.write( "6x = 12 = 180 degrees
\n" ); document.write( "6x =192
\n" ); document.write( "x = 28
\n" ); document.write( "============================================
\n" ); document.write( "A = 64 degrees
\n" ); document.write( "B = 32 degrees
\n" ); document.write( "C = 84 degrees
\n" ); document.write( "==========================================
\n" ); document.write( "64 + 32 + 84 = 180 degrees. This does check.
