You are taking your first hot-air balloon ride. Your friend is standing on level ground,100 feet away from your point of launch, making a video of the terrified look on your rapidly ascending face. How rapidly? At one instant, the angle of elevation from the video camera to your face is 31.7°.One minute later, the angle of elevation is 76.2°.How far did you travel, to the nearest tenth of a foot, during that minute?
The angle of elevation θ of the sun in the sky at any latitude L is calculated with the formula sinθ=cosDcosLcosω+sinDsinL.   ω is the number of radians that the Earth has rotated through since noon when ω=0. D is the declination of the sun. Westville has latitude L=37.9°.   Find the angle of elevation θ in degrees of the sun at 3 PM on February​ 29, 2012, where at that time D≈−0.1425 and
