# How do you find height and distance in trigonometry?

## How do you find height and distance in trigonometry?

To find the height we use trigonometry because the surface of the ground, the height of Minar and the line of elevation all together form a right angle triangle with 90 degrees between the Minar and the ground. Distance is usually the ‘base’ of the right-angled triangle formed by the height of Minar and line of sight.

**How do you solve height and distance problems?**

Q 1 – From a point 375 meters away from the foot of a tower, the top of the tower is observed at an angle of elevation of 45°, then the height (in meters) of the tower is? Let h be the height of tower From figure. 20 =h ( cot30 – cot60) 20 =h (√3-1/√3) => 20√3 = h (3-1) => h=10√3.

**Is height directly proportional to distance?**

Object distance is inversely proportional to image distance. Object height is directly proportional to image height.

### How do you find height with angle and distance?

The height of an object is calculated by measuring the distance from the object and the angle of elevation of the top of the object. The tangent of the angle is the object height divided by the distance from the object. Thus, the height is found.

**What is the formula of height and distance?**

As it is visible from the figure, the vertical from object makes an right angle with the horizontal. So if we know the height of the object and the linear distance, we can easily find out the angle by trigonometric formula. It is given by tan = Height / distance .

**What are the trigonometry problems for height and distance?**

In second quadrant, only sin and cosec are positive. In third quadrant, only tan and cot are positive. In fourth quadrant, only cos and sec are positive. Problems on height and distances are simply word problems that use trigonometry. Here, θ1 is called the angle of elevation and θ2 is called the angle of depression.

#### How to solve simple word problems in trigonometry?

Most of the simple word problems in trigonometry can be solved by the method illustrated in the example above. Many questions on Heights and Distances in Trigonometry along with their solutions are available in the practice exercise.

**How to calculate the unknown dimension in trigonometry?**

Denote the unknown dimension by say h if you are calculating height or by x if you are calculating distance. Identify which trigonometric function represents a ratio of the side about which information is given and the side whose dimensions we have to find out. Set up a trigonometric equation.

**How is trigonometry used in the real world?**

For example, trigonometry was used to find the distance of stars from the Earth. Even today, in spite of more accurate methods being available, trigonometry is often used for making quick and simple calculations regarding heights and distances of far-off objects.
