<reasoning>

Identify the sides of the right triangle relative to angle B

\[

$$\begin{aligned} &\text{Adjacent side to } B = 12\\ &\text{Opposite side to } B = 5\\ &\text{Hypotenuse} = 13 \end{aligned}$$

\]

Apply the cosine ratio formula

\[
\cos(B) = \frac{\text{Adjacent}}{\text{Hypotenuse}} = \frac{12}{13}
\]
