The value of the tangent of an angle is the ratio (opposite side) / (adjacent side).
Here you see that the opposite side (opposite to Angle B) is of length 5 and the adj. side has length 12.
Thus, the tan of Angle B is 5/12. (answer)
The answer is:
A. 10
This is because segment AB is parallel to segment DC, meaning they are the same length.
