1. The problem is to find the value of $\theta$ given some context or equation involving $\theta$. 2. To solve for $\theta$, we need an equation or expression where $\theta$ is the unknown. 3. Common formulas involving $\theta$ include trigonometric equations like $\sin(\theta) = x$, $\cos(\theta) = y$, or $\tan(\theta) = z$. 4. Without a specific equation or context, we cannot determine a unique value for $\theta$. 5. Please provide the equation or context where $\theta$ appears so we can solve for its value.
