Answer:
See below.
Step-by-step explanation:

First, use the co-function identity:

We can turn the second term into cosine:

Substitute:

Now, use the sum to product formulas. We will use the following:

Substitute:

Use the even-odd identity:

Therefore:

Replace the second term with the original term:

Proof complete.
That’s the answer just make it into a fraction it is already simplified
Volume = length x width x height
Volume = 33 x 29 x 18
= 17,226
Number of whole cubes formed by the defined volume = 17,226/3
= 5742 cubes
Answer:
6
Step-by-step explanation:
The diagonals of a parallelogram bisect each other.
The diagonals are PN and MO. The point A divides PN into 2 equal segments as well as MO into 2 equal segments.
Since AO = 6, MA should also be equal. Hence, MA (or AM) = 6.
The correct answer is AM = 6
