Two people decide to estimate the height of a flag pole. One person positions himself due north of the pole and the other person stands due east of the pole. If the two people are the same distance from the pole and 23 feet from each other, find the height of the pole if the angle of elevation from the ground at each person's position to the top of the pole is 58° (see the figure). Apply the rules regarding the use of significant digits when determining your answer.
