Let's consider a code example showing what would be allowed (or not) using different levels of inheritance: 1  class BaseClass {}; void freeStandingFunction(BaseClass* b); class DerivedProtected : protected BaseClass { DerivedProtected() { freeStandingFunction(this); // Allowed } };
Definition of Horizontal Axis. Horizontal means flat or level. Horizontal axis is the x-axis on a graph. The blue number line in the figure below is the x-axis, the horizontal axis.
Typically, horizontal angles are measured in degrees, from 0 to 360. An angle of 90 degrees would be a right angle, which is formed by two perpendicular lines. If an individual took the horizontal angle of his line of sight when looking straight north and straight east, this would measure 90 degrees.epeat this process for the second object you are making a line of sight with. The difference between their azimuths is the horizontal angle. Repeat this step for each horizontal angle you wish to measure. Add up the relevant horizontal angles.
