Answer:
C
Explanation:
The Triangle Angle Bisector theorem says that and angle bisector will divide the opposite side into 2 segments that are proportional to the other 2 sides of the triangle.
Thus, from the definition, we can say 28 and x is proportional to 14 and 8.
We can set up a ratio, cross multiply, and solve for x:

So the value of x is 16 and thus the correct answer is C
