let x be the smaller angle.
\n" ); document.write( "let x+20 be the larger angle.
\n" ); document.write( "x+(x+20) =180
\n" ); document.write( "2x=180-20
\n" ); document.write( "2z=160
\n" ); document.write( "x=160/2
\n" ); document.write( "x=80 ans. for the smaller angle.
\n" ); document.write( "80+20=100 ans. for the larger angle.
\n" ); document.write( "Proof:
\n" ); document.write( "80+100=180
\n" ); document.write( "180=180
\n" ); document.write( "
