The triangle given in the exercise is a Right Triangle because it has an angle that measures 90 degrees.

Then, you can use the following Inverse Trigonometric Function to find the measure of the angle Z:


\beta=\tan ^(-1)((opposite)/(adjacent))

In this case, you can identify that:


\begin{gathered} \beta=m\angle Z \\ opposite=25 \\ adjacent=28 \end{gathered}

Therefore, substituting values and evaluating, you get:


\begin{gathered} m\angle Z=\tan ^(-1)((25)/(28)) \\ \\ m\angle Z\approx41.76\degree \end{gathered}

Hence, the answer is: Option C.
