$\"4%2F5=X%2FY\"$
\n" ); document.write( "So then,
\n" ); document.write( " $\"4Y=5X\"$
\n" ); document.write( " $\"Y=%284%2F5%29X\"$
\n" ); document.write( "Since it's a parallelogram,
\n" ); document.write( " $\"X%2BY%2BY%2BX=360\"$
\n" ); document.write( " $\"X%2BY=180\"$
\n" ); document.write( " $\"X%2B%284%2F5%29X=180\"$
\n" ); document.write( "Now solve for $\"X\"$ .
\n" ); document.write( "Then go back and solve for $\"Y\"$ \n" ); document.write( "
