Benjamin is trying to find the height of a radio antenna on the roof of a local building. He stands at a horizontal distance of 25 meters from the building.
The angle of elevation from his eyes to the roof (point A) is 28°, and the
angle of elevation from his eyes to the top of the antenna (point B) is 40°. If
his eyes are 1.52 meters from the ground, find the height of the antenna (the
distance from point A to point B). Round your answer to the nearest meter if
necessary. A
