Ladder length= 5m
\n" ); document.write( "Distance from wall= 1.8m
\n" ); document.write( "Height ladder reaches on wall x m
\n" ); document.write( "
\n" ); document.write( "By Pythagoras theorem
\n" ); document.write( "Hypotenuse^2 = Leg1^2+leg2^2
\n" ); document.write( "5^2-1.8^2=x^2
\n" ); document.write( "25-3.24 =x^2
\n" ); document.write( "21.76=x^2
\n" ); document.write( "\"+sqrt%28x%5E2%29=sqrt%2821.76%09%29\"
\n" ); document.write( "x= 4.66 m
\n" ); document.write( "
