angle pairs are complementary or suplementary angles, or vertical angles.
Complementary angles: the sum between them is 90°
Suplementary angles: the sum between them is 180°
Vertical angles: are angles oppsite to a vertex, and they have the same value (they are congruent).
In this case, first we need to identify which angles are the same. We can see this in the following image:
The angles marked in red represent angles that have the same value (this is considering that the two verticual lineas are parallel to each other).
This way we can see that 106° and n are vertical angles, and thus, the value of n is 106°.
