X+Y=180 OR X=180-Y
\n" ); document.write( "X=.2(3Y)
\n" ); document.write( "180-Y=.6Y
\n" ); document.write( "1.6Y=180
\n" ); document.write( "Y=180/1.6
\n" ); document.write( "Y=112.5 FOR THE LARGER ANGLE.
\n" ); document.write( "X=.2(3*112.5)
\n" ); document.write( "X=.2(337.5)
\n" ); document.write( "X=67.5 FOR THE SMALLER ANGLE.
\n" ); document.write( "PROOF
\n" ); document.write( "112.5=67.5=180
