let wire length be x
\n" ); document.write( "The rope the floor & the pole form a right triangle.
\n" ); document.write( "The base is one leg The height is the other \r
\n" ); document.write( "\n" ); document.write( "By Pythagoras theorem
\n" ); document.write( "Hypotenuse^2 = Leg1^2+leg2^2
\n" ); document.write( "\"%09x+%09%5E2%09=%0930%09%5E2%09%2B%0940%09%5E2\"
\n" ); document.write( "x ^2 = 900 + 1600
\n" ); document.write( "x ^2 = 2500
\n" ); document.write( "\"+sqrt%28x%5E2%29=%09%09sqrt%28%092500%09%29\"
\n" ); document.write( "x= 50 m
