Aplane is flying at an altitude of 32,000 feet. the distance between the plane and a radio tower on the ground is 50,000 feet. what is the angle of depression between the plane and radio tower (round to 1 decimal place)?

Acar travels at an average speed of 52 miles per hour. how long does it take to travel 299 miles

Ineed in figuring out this problem.

Abird on top of a 200 ft bridge tower sees a man standing on the lower part of the bridge (which is 50 ft above the ground). the angle of depression from the bird is 26 ̊. how far is the man from the base of the bridge tower? with explanation and pictures .
