*68. mmh A kite is hovering over the ground at the end of a straight 43-mline. The tension in the line has a magnitude of 16 N. Wind blowing onthe kite exerts a force of 19 N, directed 56° above the horizontal. Note thatthe line attached to the kite is not oriented at an angle of 56° above thehorizontal. Find the height of the kite, relative to the person holding theline.
