Derive a formula to calculate the height of the top of a hill on a roller coaster using triangulation. Final answer should be in terms of d, angle 1, and angle 2. There are two points on the ground. Angle 1 is the angle formed between the ground and a line that goes from the point closer to the hill to the top of the hill. Angle 2 is the angle formed between the ground and a line that goes from the point further away to the top. d is the distance between the two points.
