X+Y=180
\n" ); document.write( "X=3Y+30
\n" ); document.write( "(3Y+30)+Y=180
\n" ); document.write( "4Y=180-30
\n" ); document.write( "4Y=150
\n" ); document.write( "Y=150/4
\n" ); document.write( "Y=37.5 FOR THE SMALLER ANGLE.
\n" ); document.write( "X=3*37.5+30
\n" ); document.write( "X=112.5+30
\n" ); document.write( "X=142.5 FOR THE LARGER ANGLE.
\n" ); document.write( "PROOF:
\n" ); document.write( "37.5+142.5=180
\n" ); document.write( "180=180
