Question 33
TrigonometryGiven that cos x = 12/13, evaluate (1 − tan x)/tan x.
- A.5/13
- B.5/7
- C.7/5
- D.13/5
Show the answer and explanation
Answer: C (7/5)
Explanation
tan x = 5/12, so (1 − 5/12)/(5/12) = (7/12) × (12/5) = 7/5.
Given that cos x = 12/13, evaluate (1 − tan x)/tan x.
Answer: C (7/5)
tan x = 5/12, so (1 − 5/12)/(5/12) = (7/12) × (12/5) = 7/5.
