Vertical angles created by the intersection of two lines are congruent.
The two missing angles for the triangle containing angle with measure \(x\) are vertical angles with measures 50, and 55.
Sum of angles in a triangle is 180
50 + 55 + x = 180
x = 75

We see that the other two angles in the same triangle with x are 50 and 55, and thus x is 180 - (50 + 55) = 180 - 105 = 75.
Answer: B
