Answer:

$(a)\ \tan A = \frac{5}{12}$

$(b)\ \cos B = \frac{5}{13}$

Step-by-step explanation:

Given

See attachment for triangles

Solving (a)

$\tan(A)$

The tan of an angle is:

$\tan(\theta) = \frac{Opposite}{Adjacent}$

From the given triangle.

$Opposite = 5$

$Adjacent = 12$

So, we have:

$\tan A = \frac{5}{12}$

Solving (b)

$\cos(B)$

The cos of an angle is:

$\cos(\theta) = \frac{Adjacent}{Hypotenuse}$

From the given triangle.

$Adjacent = 5$

$Hypotenuse = 13$

So, we have:

$\cos B = \frac{5}{13}$
