\n" ); document.write( ":
\n" ); document.write( "Two angles that are supplementary, add up to 180, therefore
\n" ); document.write( "(x+60) + (x+10) = 180
\n" ); document.write( "2x + 70 = 180
\n" ); document.write( "2x = 180 - 70
\n" ); document.write( "2x = 110
\n" ); document.write( "x = 110/2
\n" ); document.write( "x = 55
\n" ); document.write( "
\n" );
