Mathematics

D) y = 12

Step-by-step explanation:

One can use the angle bisector theorem to solve this problem. The angle bisector theorem states:

$\frac{a_1}{b}=\frac{a_2}{c}$

Where ( a_1 ) and ( a_2 ) are a part of the side that is intersected by the angle bisector and () and () are the other two sides in the triangle. Substitute in the given values and solve for the unknown.

$\frac{4}{8}=\frac{6}{y}$

Simplify,

$\frac{1}{2}=\frac{6}{y}$

Cross products,

12=y
