document.write( "one angle is double the measure of a second angle 
\n" );
document.write( "and 10 degrees less than the measure of the third angle
\n" );
document.write( "Let 2x, x and (2x +10) represent the angles
\n" );
document.write( "x + 2x + (2x+10)= 180°
\n" );
document.write( "5x + 10 = 180°
\n" );
document.write( "   5x = 170°
\n" );
document.write( "    x =  34°, the second angle.  the other two are 68°(2x) and 78°(2x+10)\r
