Answer 2

Answer:

Choice C

• 1

Step-by-step explanation:

Appropriate Question:

• cos x * csc x * tan x

Solution:

Rewrite csc x as

• cos x * 1/sin(x) * tan x

Solving through the laws:

• $\cfrac{ \cos(x) }{ \sin(x) } \times \tan(x)$

• $\cfrac{ \cos(x) }{ \sin(x) } \times \cfrac{ \sin(x)}{ \cos(x)}$

Canceling them;we have

• $\cfrac{ \cancel{ \cos(x)} }{ \cancel{ \sin(x)} } \times \cfrac{ \cancel{\sin(x)}}{ \cancel{ \cos(x)}}$

• $\boxed{1}$

Choice C is accurate.
