Answer:

Step-by-step explanation:
<u>Algebra Simplifying</u>
We are given the expression:

We need to repeatedly use the following identity:

For example, the first numerator has a difference of squares thus we factor as:

The first denominator can be factored also:

Applying the same procedure to all the expressions:

Simplifying all the fractions:

Since all the denominators are equal:

Simplifying:

Simplifying again:
T = 1
Thus:

You need to get rid of -6 by adding 6, you also need to add 6 to 18.
4x = 24
Now you need to get rid of the 4 attached to the variable, you do this by dividing 4 since it is multiplying, also dividing 4 and 24
x = 6
So the value of x is 6
Hope this helps! :)
Answer:
0.72
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you that the relation of interest is ...
Cos = Adjacent/Hypotenuse
Then the cosine of angle C is ...
cos(C) = CD/CB = 21/29
cos(C) ≈ 0.72
