Jun The relationship between the angle of elevation, the height of the flagpole, and the length of the shadow is represented by the equation tan 50°. When the object is below the line of vision, then the angle that the line of sight makes with the horizontal is referred to as the angle of depression.

With angles of elevation, on the off chance that two of the sides of the right- angled triangle are known, at that point the angle of depression formula is given as. The definition of Angle of Elevation : The upwards angle from the horizontal to a line of sight. If the angle goes "downwards" it is called an Angle of Depression. We can find an unknown angle in a right-angled triangle, as long as we know the lengths of two of its sides.
