(MAKE BRAINLIEST IF I HELPED)

Answer:

x=10

Step-by-step explanation::

We can use Triangle angle bisector theorem and proportions to solve this problem.  We put the small triangle side over the large triangle side

8           x+4

------ = ------------

12          2x+1

Using cross products

8(2x+1) = 12(x+4)

16x+8 =12x+48

Subtract 12x from each side

16x-12x +8 = 12x-12x+48

4x+8 = 48

Subtract 8 from each side

4x+8-8 = 48-8

4x = 40

Divide by 4

4x/4 = 40/4

x = 10
