Which angle is associated with the azimuth angle in astronomy?

The azimuth angle in astronomy is directly associated with Angle Z. In astronomical terms, the azimuth is a measure of the angle between a reference direction (typically true north) and a point in the sky, measured clockwise around the horizon. Angle Z specifically represents this direction, indicating where an object lies along the horizon in relation to true north. Understanding this relationship helps in locating celestial objects accurately in relation to the observer's position on the Earth.

The other angles mentioned do not have the same relevance to the concept of azimuth in astronomy and do not define or represent the directional measurements that are crucial when observing and mapping positions of stars and celestial events.
