Practice Question
An airplane is 5,000 ft above ground and has to land on a runway that is 7,000 ft away as shown above. Let x be the angle the pilot takes to land the airplane at the beginning of the runway. Which equation is a correct way to calculate x?
Answer Choices
- A: sin x = 5000/7000
- B: sin x = 7000/5000
- C: tan x = 5000/7000
- D: tan x = 7/5000
Correct Answer: C
Rationale: The opposite side to angle x is the height (5000 ft). The adjacent side is the horizontal distance to the runway start (7000 ft). Tangent = Opposite / Adjacent.
