Question

I need help with this question. I think I already chose the correct answer but I'm not sure.

Answer 1

Answer:

B. cosθ ≠ 0

Step-by-step explanation:

As we notice, tanθ is a fraction. Fractions are undefined when the denominator is equal to or approaching 0 because one cannot divide by zero. Thus, the denominator in this case is cosθ, and therefore it cannot equal zero for the equation to be true.
