HEIGHTS AND DISTANCE
*practice these sums after NCERT👈1
Line of Sight:
The imaginary line drawn from the eye of an observer to the object being viewed.
Horizontal Line:
A straight line parallel to the horizontal plane (ground level).
Angle of Elevation:
The angle between the line of sight and the horizontal line when the object is above the horizontal level.
Angle of Depression:
The angle between the line of sight and the horizontal line when the object is below the horizontal level.
Use sine , cosine or tangent to find the required sides using the given angles.
sine = perpedicular / hypotenuse
:: cosine = base /hypotenuse
:: tangent = perpendicular / base.
