document.write( "Let x be the angle measure.\r\n" );
document.write( "\r\n" );
document.write( "Then the measure of other angle is (x+12) degrees, according to the condition.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Since the angles are supplementary, they sum up to 180 degrees\r\n" );
document.write( "\r\n" );
document.write( "    \r\n" );
document.write( "    x + (x+12) = 180\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Simplify and solve\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    2x = 180 - 12 = 168\r\n" );
document.write( "\r\n" );
document.write( "     x            = 168/2 = 84.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "ANSWER.  The angle measure is 84°.  The other angle is  84° + 12° = 96°.\r\n" );
