Answer: 5 / 12

Explanation:

1) The function ratio tangent is defined as opposite-leg / adjacent leg:

         tan(x) = opposite-leg / adjacent leg

2) In the figure the legs related to angle A are:

         - opposite-leg: BC = 20

         - adjacent-leg: AC = 48

3) Therefore, tan(A) = 20 / 48 = 5 / 12
