Answer:

Step-by-step explanation:
Factor constant terms:

Divide both sides by -2:

Expand trigonometric functions using the fact:

So:

Factor sin(x) and constant terms and multiply both sides by -1:

Split into two equations:

For (1)
Add 1 to both sides and divide both sides by 8:

Take the inverse cosine of both sides:

For (2)
Simply take the inverse sine of both sides

Therefore, the solutions are given by:
