Answer:
x = 33 degrees.
Explanation:
You can see that there is triangle ABC. There are 180 degrees in a triangle. One angle of the triangle is 42 degrees, and the other is 105 degrees. 105 + 42 = 147. The angle at point C would then be 180 - 147 = 33 degrees.
Because lines BC and DE are parallel, you can say that the 33 degree angle and the x-degree angle are the same, since they are alternate angles. Hence, the x is 33 degrees.
