To solve this equation, we first need to isolate the cosine function.
Firstly, rewrite the equation in terms of cosine:cos(x/3 + π/6) = 2/9
Next, take the inverse cosine of both sides to remove the cosine function:x/3 + π/6 = arccos(2/9)
Now, we need to solve for x:x/3 = arccos(2/9) - π/6
Multiply both sides by 3 to isolate x:x = 3(arccos(2/9) - π/6)
Therefore, the solution to the equation is x = 3(arccos(2/9) - π/6).
