Answer 1

x = 9 units

Explanation:

This problem can be solved with the angle bisector theorem, which states that the ratio of the components on one side of the triangle is equivalent to the ratio of the components on the other side of the triangle. (In this case, the ratios would be
`(12)/(4)` and
`(x)/(3)`.

Therefore,

`(12)/(4)` =
`(x)/(3)`

and by cross multiplication, you would get x = 9
