A mini toy helicopter ascends 50 feet vertically, then flies horizontally 200 feet. Find the angle of elevation to the helicopter now as seen by an observer at the takeoff point. Round to the nearest degree

There is a right triangle with you in the lower left vertice, and the right angle between the sides 50 (vertical segment) and 200 (horizontal segment)

Then, tan (angle of elevation) = vertical / horizontal  = 50/200 = 0.25

=> angle = arc tan(0.25) = 14 degress.

Answer: 14 degrees
