This is a composite. Another way to write them is f(g(x)). Take the function g(x) and stick it in for x in f(x). Like this: 
. But we aren't done cuz there's some simplifying there to do. 
and canceling out the 3's we get just a simple x as our answer. The choice is the last one above as your answer.

Answer:
A
Step-by-step explanation:
Cosine is the ratio of "adjacent" to "hypotenuse"
With respect to the Angle E, the adjacent side is FE and the hypotenuse (always opposite side to 90 degree angle) is DE.
We are given DE = 26, but we need FE. We will solve for FE using Pythagorean Theorem, which tells us:
leg^2 + another leg^2 = hypotenuse^2
So, we will have:
10^2 + FE^2 = 26^2
Now, we solve for FE:
So,
Cos(E) = adj/hyp = 24/26
Correct answer is A
