A 6-foot-tall worker stands 40 feet away from a crumbling tower. The angle of elevation to the top of the tower is 30°, which is 15° less than in the tower's original design. (Assume the worker's height is approximately eye level).The angle of elevation to the top of the tower in the original design is The distance between the worker's eyes and the original top of the tower is feet.

A man is 550 feet from the base of a very tall building. The building is standing on a large flat area. Using a surveying instrument, he measures the angle between the ground and the top of the building from where he is standing. The angle is 57.1 degrees. How tall is the building?

Jack and Jill were on the same side of a hill but were 34 m apart. Both were lying on the ground looking up at the peak of a hill. Jill, who is closer to the hill, determined that the angle of elevation to the top was 37 degree. Jack determined that the angle of the elevation to the top from his position was 22 degree. How high is the peak of the hill

You are a secret agent trapped at the top of a tall building. To escape, you decide to slide down a zip line that goes from the top of the building to the ground at a 24° angle of depression. If the zip line ends 200 feet away from the base of the building, how long is the zip line?
