You can put this solution on YOUR website!
sqrt49/100=7/10 or .7 or 70% it is very rational.
\n" ); document.write( "------------------------------------------------------------
\n" ); document.write( "60^2+80^2=x^2
\n" ); document.write( "3600+6400=x62
\n" ); document.write( "10000=x^2
\n" ); document.write( "x=sqrt10000
\n" ); document.write( "x=100 answer. length of the diagonal.
\n" ); document.write( "------------------------------------------------------------
\n" ); document.write( "4^2+x^2=11^2
\n" ); document.write( "16+x^2=121
\n" ); document.write( "x^2=121-16
\n" ); document.write( "x^2=105
\n" ); document.write( "x=sqrt105
\n" ); document.write( "x=10.25 answer for the height up the wall for this ladder.
\n" ); document.write( "-------------------------------------------------------------
\n" ); document.write( "the distance between these two points is the diagonal formed by the right triangle with dimentions of:
\n" ); document.write( "x=(1+3)=4 & y=4+2)=6 thus usuing the pythagorean theorem a^2+b^2=c^2
\n" ); document.write( "4^2+6^2=c^2
\n" ); document.write( "16+36=c^2
\n" ); document.write( "c^2=52
\n" ); document.write( "c=sqrt52
\n" ); document.write( "c=7.2111 answer.
\n" ); document.write( "
