HERE YOU HAVE A RIGHT TRIANGLE WITH SIDE=18 FEET & THE HYPOTENUSE=BASE+6.
\n" ); document.write( "A^2+B^2=C^2
\n" ); document.write( "18^2+B^2=(B+6)^2
\n" ); document.write( "324+B^2=B^2+12B+36
\n" ); document.write( "12B=324-36
\n" ); document.write( "12B=288
\n" ); document.write( "B=288/12
\n" ); document.write( "B=24 IS THE LENGTH FROM THE FOOT OF THE LADDER TO THE BUILDING.
\n" ); document.write( "24+6=30 FEET IS THE LENGTH OF THE LADDER.
\n" ); document.write( "PROOF
\n" ); document.write( "18^2+24^2=30^2
\n" ); document.write( "324+576=900
\n" ); document.write( "900=900
\n" ); document.write( "
