the tree ,string & and the ground form a right triangle
\n" ); document.write( "string = hypotenuse = 20m
\n" ); document.write( "distance from tree =17 m
\n" ); document.write( "so height^2 = 20^2-17^2
\n" ); document.write( "=400-289
\n" ); document.write( "=111
\n" ); document.write( "height = sqrt(111)
\n" ); document.write( "= 10.5 m height of tree
\n" ); document.write( "...
