A = x
\n" ); document.write( "B = x + 10
\n" ); document.write( "C = 2(x + 10) - 30
\n" ); document.write( "====================================================
\n" ); document.write( "x + x + 10 +2(x + 10) -30 = 180
\n" ); document.write( "x + x + 10 + 2x + 20 - 30 = 180
\n" ); document.write( "4x = 180
\n" ); document.write( "x = 45 degrees. This is the first angle.
\n" ); document.write( "==================================================
\n" ); document.write( "A = 45 degrees
\n" ); document.write( "B = 45 + 10 = 55
\n" ); document.write( "B = 55 degrees
\n" ); document.write( "C = 2(55) - 30 = 80 Degrees,
\n" ); document.write( "C = 80 degrees.
\n" ); document.write( "This does check.
