Your answer for your problem
Answer:
-8
Step-by-step explanation:
D, it is the correct answer
Answer:
See below
Step-by-step explanation:
It has something to do with the<em> </em><u><em>Weierstrass substitution</em></u>, where we have

First, consider the double angle formula for tangent:

Therefore,

Once the double angle identity for sine is

we know
, but sure, we can derive this formula considering the double angle identity

Recall

Thus,
Similarly for cosine, consider the double angle identity
Thus,

Hence, we showed

![5\cos(x) =12\sin(x) +3, x \in [0, 2\pi ]](https://tex.z-dn.net/?f=5%5Ccos%28x%29%20%3D12%5Csin%28x%29%20%2B3%2C%20x%20%5Cin%20%5B0%2C%202%5Cpi%20%5D)
Solving





Just note that

Well the first part of the table is 7 cause 7x5- 35 x 6 is 42 x 7 49. Second part of the table is 8 x 5 40 x6 is 48 x 7 is 56. once you know this it is easy just to common factor it or just simply add 5 6 or 7 to the numbers already given
