What is the length of AC¯¯¯¯¯ ? Enter your answer in the box.

In the question, the angles proves that this triangle is an isoceles triangle.

So we can set the two sides equal: $x + 4 = 3x - 8$

Add $-x+8$ to both sides of the equation: $12 = 2x$

Divide both sides by 2: $x = 6$

We find that $x=6$ . AC is also x, so, it is 6 too.
