Learn what is angle of elevation, how to calculate it using trigonometry, and see examples of its applications. Find out the difference between angle of elevation and angle of depression, and how to solve problems involving them.
The angle of elevation is the angle between the horizontal line and the line of sight which is above the horizontal line. It is formed when an observer looks upwards. Suppose you are standing at the terrace of a building and looking upwards at the sky or at the sun or moon.

In mathematics and physics, trigonometry has its applications. Mathematical concepts like height, distances, angle of elevation, and angle of depression are examples of applications of trigonometry. Let us imagine; for example, an observer is looking at an aircraft—an angle of elevation formed towards the aircraft from the observer’s view. The angl...
Definition
The angle generated by the line from an object to the observer’s eye and the horizontal lineor plane is known as the angle of elevation. The line of sight is the line the observer’s eye is on. As the word says, the angle of elevation is thus formed so that it is above the observer’s eye. For example, an observer is looking at an object, as shown in the figure below. The angle of elevation is represented by θ. Here, a right-angle triangle is created if we connect the object vertically and the...
There are formulas that will help us calculate the angle of elevation. Let us refer to the figure below to show how we use the formulas. Recall that a right-angle triangle is formed if an imaginary line is drawn connecting the object and the horizontal line’s end. As a result, we may use the trigonometry concept to determine how distant the observe...
Angles of elevation and depression are opposites of one another. The object is positioned above the observer at an angle of elevation, whereas it is positioned below the observer at an angle of depression. The angle of elevation is generated if you are standing and looking at an object on the rooftop. Whereas, if you were to look at the plants on t...
Example 1 Find the value of the angle of elevation ( θ ) in each of the given figures. Solution ( a ) In the given triangle ABC, ∠A is the angle of elevation, side AC is the opposite side, while side BC is the adjacent side of the angle θ. Since we know two sides of the triangle, opposite and the adjacent sides of the angle θ, we must use the formu...
Angle of Elevation
The angle generated by the line from an object to the observer’s eye and the horizontal line or plane is known as the angle of elevation of the object as sighted by the observer. The line of sight is the line that the observer’s eye is on. As the word says, the angle of elevation is thus formed so that it is above the observer’s eye.
The Angle of Elevation Formulas
To determine the angle of elevation, we can use the formulas below, provided we know the angles’ two sides.
What is meant by angle of elevation?
The angle generated by the line from an object to the observer’s eye and the horizontal line or plane is known as the angle of elevation of the object as sighted by the observer. The line of sight is the line that the observer’s eye is on. The angle of elevation is thus created, as the word “elevation” suggests, so it is above the observer’s eye.
What differentiates the angle of elevation from the angle of depression?
Angles of elevation and depression are opposites of one another. The object is positioned above the observer at an angle of elevation, whereas it is positioned below the observer at an angle of depression. The angle of elevation is generated if you are standing and looking at an object on the rooftop. On the other side, if you were to gaze at the plants on the ground, an angle of depression would be generated. The table below shows the essential difference between the angle of elevation and t...
In a triangle, what is the angle of elevation?
In terms of angle of elevation, the right-angle triangleis formed if an imaginary line is drawn connecting the object and the horizontal line’s end. As a result, we may use the trigonometry concept to determine how distant the observer is from the object. The horizontal line will be regarded as the adjacent side of the constructed triangle, and the height of the object will be looked at as the opposite side of θ.
Learn what angle of elevation is, how to calculate it using trigonometry, and how it differs from angle of depression. See examples, formulas, and diagrams to understand the concept and applications of angle of elevation.
Learn what the terms angle of elevation and angle of depression mean. The words may be big but their meaning is pretty basic!
- Unless you are trying to code or take engineering as a career you likely won't come in contact with it.
- from Emma's perspective it creates a nice 30-60-90 triangle with leg opposite the 60 degree is 90 meters so the leg opposite 30 degrees is 30sqt(3)...
- It’s going to be used in word problems and what not. As a result of that, Khan is telling us what the vocab means so we understand better.
- You can use the inverses of SIN, COS, and TAN, (arcsin, arccos, and arctan) to calculate a degree from given side lengths.
- that is a great question! I love the pythagorean theorem... it is a^2 + b^2 = c^2
- Note the definition of angle of depression again: The angle of depression is the angle between the horizontal line and the observation of the objec...
- Well basically, if your looking at something diagonally above you, you form a "sight line". The angle that would form if it was a real line to the...
- GPS uses trig, Rocket launches and space exploration uses trig, surveyors use trig. So every time you try to get to somewhere, remember that trig i...
- Yes, they will be equal if the "sky line" and the "ground line" are parallel lines.
- Here’s one example. I just took down a dead tree with the use of a clinometer and a simple trigonometric function (angle of elevation). The mathema...
An angle of elevation (also called an angle of inclination) is an angle that goes above the horizontal from whatever is the vantage point. For instance, suppose you are standing on the sidewalk looking up at the top of the chimney on the house across the street.
