\n" ); document.write( " $\"WY\"$ and $\"VZ\"$ intersect at point $\"X\"$
\n" ); document.write( "measure of angle $\"WXV=4s-9\"$
\n" ); document.write( "measure of angle $\"ZXY=2s%2B17\"$
\n" ); document.write( "Prove $\"s=13\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"WXV\"$ and $\"ZXY\"$ are $\"vertical\"$ $\"+angles\"$ , the angles opposite each other when two lines cross, and they are equal \r
\n" ); document.write( "\n" ); document.write( " $\"WXV=ZXY\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"4s-9=2s%2B17\"$ \r
