A = x - 5
\n" ); document.write( "B = x
\n" ); document.write( "C = x + 12
\n" ); document.write( "x - 5 + x + x + 12 = 180
\n" ); document.write( "3x + 7 = 180
\n" ); document.write( "3x = 173.
\n" ); document.write( "B = 57.7 degrees
\n" ); document.write( "A = 52.7 degrees
\n" ); document.write( "C = 69.7 degrees
\n" ); document.write( "57.7 + 52.7 + 69.7 = 180.1 degrees, approx 180 degrees with a round off error.
