1. The problem is to find $\tan A$ given an angle $A$. 2. Recall the definition of tangent in a right triangle: $\tan A = \frac{\text{opposite}}{\text{adjacent}}$. 3. Without additional information about the triangle or angle $A$, we cannot compute a numeric value. 4. If you provide the lengths of the sides or the value of $A$, we can calculate $\tan A$. 5. Please provide more details to proceed with the calculation.
