\n" ); document.write( "\n" ); document.write( "x = the angle
\n" ); document.write( "90 - x = complement {complementary angles add up to 90}
\n" ); document.write( "180 - x = supplement {supplementary angles add up to 180}\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "2(90 - x) = 180 - x - 30 {twice its complement is 30 less than its supplement}
\n" ); document.write( "180 - 2x = 150 - x {used distributive property and combined like terms on right}
\n" ); document.write( "30 - 2x = -x {subtracted 150 from both sides}
\n" ); document.write( "x = 30 {added 2x to both sides}\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "30 is the angle
