Have you ever wondered how to determine the length of side B in a figure? It can be a tricky task, but with the right approach, it’s possible to find the solution. Let’s dive in and explore the steps involved in finding the length of side B.

**Understanding the Problem**

Before we delve into the calculations, it’s important to understand the problem at hand. The key to finding the length of side B lies in identifying the relationships between the different sides and angles of the figure. If you’re having trouble grasping the concept, don’t worry, we’ll break it down step by step.

**Calculating the Length of Side B**

To calculate the length of side B, we need to determine the relationships between the different sides and angles of the figure. By applying trigonometric ratios or geometric principles, we can derive the formula for finding the length of side B. It’s important to note that the specific formula used will depend on the given information and the type of figure involved.

**Summarizing the Main Points**

In summary, finding the length of side B in a figure requires a systematic approach. By understanding the relationships between the different sides and angles, we can apply trigonometric ratios or geometric principles to derive the appropriate formula. Whether you’re dealing with right triangles, parallelograms, or other geometric shapes, the key is to identify the relevant relationships and apply the correct formula.

**Determining the Length of Side B in a Right Triangle**

**Introduction**

In a right triangle, the Pythagorean theorem states that the square of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides (the legs). This theorem provides a valuable tool for solving problems involving right triangles.

**Given Information**

Given a right triangle with:

- Side A = 3 units
- Side C (hypotenuse) = 5 units

**Determining Side B**

To find the length of side B, we can use the Pythagorean theorem:

```
c^2 = a^2 + b^2
```

where:

- c = hypotenuse
- a and b = legs

Substituting the given values:

```
5^2 = 3^2 + b^2
```

```
25 = 9 + b^2
```

```
b^2 = 25 - 9
```

```
b^2 = 16
```

```
b = sqrt(16)
```

**Conclusion**

Therefore, the length of side B in the given right triangle is **4 units**.
