Application of Trigonometry
Application of Trigonometry
- Find height of tall building or tower without actually measuring it
- Find the height at which an object , airplane or balloon is flying
- Find the distance of a vehicle or ship from a tower.
- Used extensively in the field of construction.
- Construct map
- Determine position of a place in a Map using latitude & Longitude
- Astronomers use it to calculate distances from the Earth to the planets and stars.
Angle of Elevation & Depression
The angle of depression of a point on the object being viewed is the angle formed by the line of sight with the horizontal when the point is below the horizontal level, i.e., the case when we lower our head to look at the point being viewed.
Numerical: The angle of elevation of the top of a tower from a point on the ground, which is 30 m away from the foot of the tower, is 30°. Find the height of the tower.
Thus height of tower is 10√3 m.
