Practice Question
Which equation is a correct way to calculate x?
Answer Choices
- A: sin x=5,000 /7,000
- B: sin x= 7,000 /5,000
- C: tan x= 5,000/7,000
- D: tan x=7,000/5,000
Correct Answer: C
Rationale: Form a right triangle: opposite = 5,000 ft (height), adjacent = 7,000 ft (runway). Angle x is at the plane. Tan x = opposite/adjacent = 5,000/7,000. Thus, the correct answer is tan x= 5,000/7,000.
