document.write( "Let x be the measure of the smallest angle.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then the largest angle's measure is 9x, according to the condition,\r\n" );
document.write( "\r\n" );
document.write( "and the third angle is 2x.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Further, the sum of interior angles of each triangle is 180 degrees, which gives you an equation\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "x + 2x + 9x = 180  ====>  12x = 180  ====>  x =  = 15 degrees.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Answer.  The angles are  15 degrees, 30 degrees and 9*15 = 135 degrees.\r\n" );
