ANGLES OF ELEVATION AND DEPRESSION (PART 1)
Angles of Elevation and Depression (Part 1)
The angles of elevation and depression are used to describe the inclination or declination of a line of sight relative to the horizontal.
- Angle of Elevation: This is the angle formed when an observer looks upward at an object higher than their eye level.
- Angle of Depression: This is the angle formed when an observer looks downward at an object lower than their eye level.
In both cases, the horizontal line from the observer’s eye serves as the reference. These angles are commonly applied in solving real-world problems involving heights and distances, such as determining the height of a building, the distance to a ship, or the depth of a valley. By applying trigonometric ratios like sine, cosine, and tangent, these problems can be solved efficiently.
