Find the value of x need answer very lost asap

This problem uses the Angle Bisectir Theorem, which states that (in this problem):

The side measuring 12 over the side measuring 8 is equal to the side measuring x over the side measuring 6.

Basically, we can write this as a proportion:

12/8 = x/6

Cross multiply:

8x = 72

Divide both sides by 8:

x = 9

The answer is (D), x = 9.

the answer is b.

step-by-step explanation:

identity property is where 0+whatever number=whatever number. basically 0+ a number.
