2x+5x+40=180
\n" ); document.write( "7x=180-40
\n" ); document.write( "7x=140
\n" ); document.write( "x=140/7
\n" ); document.write( "x=20
\n" ); document.write( "2*20=40 degrees for the smaller angle.
\n" ); document.write( "5*20+40=100+40=140 degrees for the larger angle.
\n" ); document.write( "40+140=180
\n" ); document.write( "180=180\r
