Angle of depression formula

Learn in detail the definition, formula and solve word. Learn what the terms angle of elevation and angle of depression mean. The words may be big but their meaning is pretty basic!

The angle of elevation of an object as seen by an observer is the angle between the horizontal and the line from the object. The angle of depression is the angle between a horizontal line from the observer and the line of sight to an object that is below the horizontal line.

Recall the three trigonometric ratios (or identities), sine, cosine, and tangent. They each are the mathematical. For example, if you were. Learn how to solve the word problems with trigonometry.
