Algebra.Com's Answer #310515 by Gogonati(855) 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. \n" ); document.write( " |
