As shown in the left figure, a person looking at the top of a building from point P looks with an angle of elevation of 28°. A person of the same height at point Q, which is 25 m closer to the building, has to look up with an angle of elevation of 58°. By making a scaled construction, the right figure was drawn. Assuming the people are 1.5 m tall, how tall is the building?
