Answer:

Step-by-step explanation:
We want to evaluate the following limit.

We need to recall that, limit of a sum is the sum of the limit.
So we need to find each individual limit and add them up.

Recall that, as
and the limit of a constant, gives the same constant value.
This implies that,

This gives us,

The correct answer is D
Answer:
The answer to your question is AC = 9.9
Step-by-step explanation:
To solve this problem use trigonometric functions. The trigonometric function that relates the hypotenuse and the adjacent side is cosine.
cos α = 
Solve for hypotenuse

Substitution
hypotenuse = 
Simplification and result
hypotenuse = 9.85
