The correct answer is Longitudinal degree
Step-by-step explanation:
The coordinate 125° West shows the location of a place in reference to East vs West. This feature is part of longitude, which uses vertical imaginary lines known as meridians to determine whether places are in the East or West, and it is the opposite of latitude. Moreover, longitude is represented through grades from 0°, which is an imaginary line known as the Prime Meridian to 180°. In this context, the coordinate given refers to the longitudinal degree.
