Let the angle = \"+a+\"
\n" ); document.write( "It's supplement = \"+180+-+a+\"
\n" ); document.write( "given:
\n" ); document.write( "\"+a+%2F+%28+180-a+%29+=+2%2F7+\"
\n" ); document.write( "\"+7a+=+2%2A%28+180+-+a+%29+\"
\n" ); document.write( "\"+7a+=+360+-+2a+\"
\n" ); document.write( "\"+9a+=+360+\"
\n" ); document.write( "\"+a+=+40+\"
\n" ); document.write( "----------
\n" ); document.write( "\"+a+%2F+%28+90+-+a+%29+=+40+%2F+%28+90+-+40+%29+\"
