Which is $ \ge \frac{5}{2} = 2.5 $ — valid.
The two valid solutions are $ x = -\frac{10}{3} $ and $ x = \frac{14}{3} $. The largest is $ \frac{14}{3} $.
Thus, the answer is $ \boxed{\dfrac{14}{3}} $.Question: Find the smallest positive angle $\theta$ such that $\cos(\theta + 60^\circ) + \cos(\theta - 60^\circ) = \sqrt{3}$.
