Set 2: Trigonometry (Advanced)

[Variation 1] **Choice A is the best answer.** tan = sin/cos = (8/17) / (15/17) = 8/15

Explanation

Answer: A

PROBLEM

Recent studies show that if sin(theta) = 8/17 and cos(theta) = 15/17, find tan(theta).

If sin(theta) = 8/17 and cos(theta) = 15/17, find tan(theta).

8/15

✓ Correct

8/17

17/15

15/8

Detailed Explanation

[Variation 1] Choice A is the best answer. tan = sin/cos = (8/17) / (15/17) = 8/15

Why others are wrong:

B: 8/17 is incorrect because it does not satisfy the equation.

C: 17/15 is incorrect because it does not satisfy the equation.

D: 15/8 is incorrect because it does not satisfy the equation.
