So,
We're going to find the value of side AB first:
Using the pythagorean theorem, we got:
![\begin{gathered} (AB)^2=(37)^2-(12)^2 \\ (AB)^2=1369-144 \\ (AB)^2=1225 \\ AB=\sqrt[]{1225} \\ AB=35 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/pebomy1dwdd269ak9chmz4osv5onsyghon.png)
Now, remember that the tangent function is the ratio between the opposite side of the angle given and its adjacent side. Then,

Therefore, the correct answer is B.
