Question 1 • 25-26 CRX Math Models with Applications 7052A

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.

Answer
A
75º
B
15º
C
76º
D
14º

Explanation

The helicopter is 50 feet above the takeoff point and 200 feet horizontally away, so these form the opposite and adjacent sides of a right triangle. The angle of elevation θ satisfies tan(θ) = 50/200 = 0.25, giving θ ≈ 14° when rounded to the nearest degree. The correct choice is 14º.
