Let the broken part length be y
\n" ); document.write( "let the remaining lenngth be x
\n" ); document.write( "distance from base of pole = 20ft\r
\n" ); document.write( "\n" ); document.write( "they form a right triangle\r
\n" ); document.write( "\n" ); document.write( "\"y%5E2=x%5E2%2B%2820%29%5E2\" by Pythagoras theorem\r
\n" ); document.write( "\n" ); document.write( "\"y%5E2-x%5E2=400\"\r
\n" ); document.write( "\n" ); document.write( "Second condition\r
\n" ); document.write( "\n" ); document.write( "it breaks 5feet below\r
\n" ); document.write( "\n" ); document.write( "The broken part length = y+5
\n" ); document.write( "The remaining part length =- x-5
\n" ); document.write( "distance from base of pole = 30 ft
\n" ); document.write( "\"%28y%2B5%29%5E2=+%28x-5%29%5E2%2B%2830%29%5E2\"
\n" ); document.write( "\"y%5E2%2B10y%2B25+=+x%5E2-10x%2B25%2B900\"\r
\n" ); document.write( "\n" ); document.write( "\"y%5E2-x%5E2=+-10x-10y%2B900\"\r
\n" ); document.write( "\n" ); document.write( "\"400=+-10x-10y%2B900\"\r
\n" ); document.write( "\n" ); document.write( "10x+10y=500
\n" ); document.write( "/10
\n" ); document.write( "x+y= 50 \r
\n" ); document.write( "\n" ); document.write( "But x+y is the length of the flag pole\r
\n" ); document.write( "\n" ); document.write( "
