if the exterior angles x y z
\n" ); document.write( "of a triangle are in the ratio 4:5:6 what is the ratio of the interior
\n" ); document.write( "angles a b c.
\n" ); document.write( "--------------
\n" ); document.write( "The sum of the exterior angles = 360 degs
\n" ); document.write( "4x + 5x + 6x = 360
\n" ); document.write( "15x = 360
\n" ); document.write( "x = 24
\n" ); document.write( "Angles are 96, 120 & 144 degs
\n" ); document.write( "Interior angles are 84, 60 & 36
\n" ); document.write( "--> 7:5:3
\n" ); document.write( "
\n" ); document.write( "
