You can put this solution on YOUR website!
Let's be the unknown angel x degree, then its supplement will be (180-x) degree\r
\n" ); document.write( "\n" ); document.write( "write as you read the equation: x=3(180-x)-28, solving this equation, we get:\r
\n" ); document.write( "\n" ); document.write( "x+3x=540-28 => 4x=512 => x=128.\r
\n" ); document.write( "\n" ); document.write( "Answer:The unknown angle is 128 degree.
