B
Step-by-step explanation:
The triangle shown is an isosceles triangle. This means that two angle measures and two sides are the same. You can determine this by seeing that the two angles on each side are 50 degrees, identical.
With this information, you can also determine that AB and BC are equal, leading you to this equation:
4x = 2x + 6
Solving for x will get you x = 3.
However, the length of AB is 4x, so you must multiply 4 by 3 to get your answer.
