Study Notes
Trigonometry Applications
- Trigonometry is used to calculate heights and distances.
- The line of sight is drawn from the observer's eye to the object.
- The angle of elevation is the angle between the line of sight and the horizontal.
- The angle of elevation is measured from the horizontal up towards the object.
- An observer is looking at an object, the angle of the line of sight with the horizontal is termed as the angle of elevation from the observer's eye to the point observed on the object.
- The figure (Fig. 9.1) displays the line of sight (AC) from the student's eye to the top of the minar. The angle BAC is the angle of elevation
