The two angles have a ration of 3:6.
\n" ); document.write( "The two angles are supplements to they total 180 degrees.
\n" ); document.write( "The ratio of 3:6 means the 180 degrees has been split into 3+6 = 9 parts.
\n" ); document.write( "180/9 = 20 degrees per part
\n" ); document.write( "One angle is 3 parts, so it = 3*20 = 60 degrees.
\n" ); document.write( "The other is 6 parts, so it = 6*20 = 120 degrees.
\n" ); document.write( "
\n" );
