# 10th Class Chapter No 21 - Height and Distance in Maths for ICSE

#### Angle of elevation

• The line of sight is the line drawn from the eye of an observer to the point on the object viewed by the observer (the line AB)
• Angle of elevation(BAC) is the angle between the horizontal and the line of sight to an object above the horizontal.

#### Angle of depression

Angle of depression is the angle between the horizontal and the line of sight to an object beneath the horizontal.
Using trigonometric ratios like tan θθ and cot θθ, we can compute the height or length of an object or the distance between two distant objects.
