in triangle XYZ, the length of side XY is twice the length of side XZ and three
\n" ); document.write( " less than the length of side YZ. if the perimeter of the triangle is 33,
\n" ); document.write( "what is the length of its sides?
\n" ); document.write( ":\r
\n" ); document.write( "\n" ); document.write( "\"the length of side XY is twice the length of side XZ\"
