Angles of Elevation and Depression
- Angle of elevation refers to the upward angle from a horizontal line to an object above it.
- Angle of depression refers to the downward angle from a horizontal line to an object below it.
Calculating Height using Angle of Elevation
- If the angle of elevation from a person to the top of an object (e.g. a tree) is known, and the person's distance from the object is also known, the height of the object can be calculated.
- Example: If the angle of elevation from a person to the top of a tree is 45 degrees, and the person is standing 20 meters away from the tree, the height of the tree can be calculated.
