Question

multiple-choice question
what relationship of angles is shown in number 2?
complementary
adjacent
vertical
supplemantary

Explanation:

Vertical angles are opposite angles formed by two intersecting lines, and they are congruent. In figure 2, $x^\circ$ and $128^\circ$ are opposite each other at the intersection of two lines, matching the definition of vertical angles. Complementary angles sum to $90^\circ$, adjacent angles share a side/vertex, and supplementary angles sum to $180^\circ$, which do not describe this pair.

Answer:

vertical
