\n" ); document.write( "the ratio of an angle to its supplement is $\"3%3A7\"$ ...->\r
\n" ); document.write( "\n" ); document.write( " $\"3x+%2B+7x+=+180\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"10x+=+180\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"x+=+18\"$ \r
\n" ); document.write( "\n" ); document.write( "and $\"3x+=+54\"$ \r
\n" ); document.write( "\n" ); document.write( "An angle and its complement always have a sum of $\"90\"$ degrees\r
\n" ); document.write( "\n" ); document.write( " $\"54+%2B+k+=+90\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"k+=+36\"$ \r
\n" ); document.write( "\n" ); document.write( "the ratio will be:\r
