To answer this question, you have that both equations can be equated since they represent the same angle since both lines are parallel. Then, we can write:

We need to solve for x, first, by subtracting x from both sides of the equation, and then subtracting 2 from both sides of the equation:


Finally, to find the value of x, we need to divide both sides by 2 as follows:

Therefore, the value for x = 13.
