To find the missing angle using the inverse tangent ratio, we use the formula:
\[ \theta = \tan^{-1}\left(\frac{\text{opposite}}{\text{adjacent}}\right) \]
However, you haven't provided the lengths of the opposite and adjacent sides, which are necessary to perform the calculation.
If you have the values for the opposite and adjacent sides, please provide them, and I can help you calculate the angle and determine which response is correct.
