a=distance from base; b=height; c=length of wire
\n" ); document.write( "\"a%5E2%2Bb%5E2=c%5E2\"
\n" ); document.write( "\"%288ft%29%5E2%2B%2818ft%29%5E2=c%5E2\"
\n" ); document.write( "\"64ft%5E2%2B324ft%5E2=c%5E2\"
\n" ); document.write( "\"388ft%5E2=c%5E2\"
\n" ); document.write( "\"sqrt%28388ft%5E2%29=c\"
\n" ); document.write( "\"19.698ft=c\" ANSWER The length of the wire would be 19.698 feet.
