According to the trigonometric functions, we can see that angle x can be found through the one that involves the adjacent side and the hypotenuse, which in this case is the cos,
then, if we apply the inverse we can find the value of x,
Answer:
Answer: Second option.
Step-by-step explanation:
Given the function f(x), which is:
And given the function g(x), which is:
You need to substiute the function into the function in order to find .
Therefore, through this procedure, you get this answer:
You can observe that this matches with the second option.
