GoMim AI | What is adjacent and How to Calculate it

Introduction

In the world of mathematics, understanding the term 'adjacent' is crucial for solving problems in geometry, trigonometry, and various other fields. Whether you're studying for an exam or working on a real-world application, knowing how to identify and calculate adjacent elements can provide clarity and insight. Let's dive into what 'adjacent' means and how you can tackle related problems effectively.

What is it?

In mathematics, the term 'adjacent' typically refers to two objects or elements that are next to each other. In geometry, it often describes sides or angles that share a common vertex or side. For example, in a right triangle, the adjacent side is the one that forms the angle of interest with the hypotenuse. The mathematical expression for the adjacent side in trigonometry, when dealing with a right triangle, can be represented as: $$\text{Adjacent Side} = \text{Hypotenuse} \times \cos(\theta)$$ where $\theta$ is the angle you are examining.

Why is it important?

Understanding the concept of 'adjacent' is pivotal in various mathematical applications. In trigonometry, identifying adjacent sides helps in determining the cosine of an angle, which is essential for solving problems related to waves, oscillations, and circles. In real-world applications, such as engineering and architecture, knowing adjacent measurements is crucial for accurate construction and design. Furthermore, in data analysis, recognizing adjacent data points can be vital for understanding trends and making predictions.

How to Calculate it Step-by-Step

Here's how you can calculate the length of an adjacent side in a right triangle using trigonometry:

1. Identify the angle ($\theta$): Determine the angle from which you want to find the adjacent side.

2. Know your hypotenuse: Make sure you have the length of the hypotenuse.

3. Use the cosine function: Use the formula $\text{Adjacent Side} = \text{Hypotenuse} \times \cos(\theta)$

4. Calculate: Plug the values into the formula and compute.

Example:

Suppose you have a right triangle with a hypotenuse of 10 units and an angle $\theta$ of 60 degrees.

- Identify the angle: $\theta = 60^\circ$

- Hypotenuse = 10

- Calculate the adjacent side: $\text{Adjacent Side} = 10 \times \cos(60^\circ) = 10 \times 0.5 = 5$

Thus, the adjacent side is 5 units.

Related Practice Problem

Problem:

You are given a right triangle where the angle $\theta$ is 45 degrees, and the hypotenuse is 14 units. Find the length of the adjacent side.

Step-by-step Solution:

1. Identify the angle ($\theta$): $$\theta = 45^\cir$$
2. Hypotenuse: The hypotenuse is 14 units.
3. Use the cosine function: Apply the formula $\text{Adjacent Side} = \text{Hypotenuse} \times \cos(\theta)$.
4. Calculate:
5. Calculate $$\cos(45^\circ) = \frac{1}{\sqrt{2}} \approx 0.707$$
6. Adjacent Side = $$14 \times 0.7071 \approx 9.89$$

The length of the adjacent side is approximately 9.899 units.
