# what’s the length of side b in the figure below?

Hello dear readers! In this post on negarinfo we are going to answer the question **“what’s the length of side b in the figure below?”**

So stay with us to the end, thanks for choosing our website.

the answer would be letter c because you have to use orders of operations io on aka A^2+B^2=C^2

how to set it up woulf look like this: a^2= 7^2

B^2=?, and C^2=13^2

in other words a=7squared

B=?

and C=13 squared

so the problem would end up like this:.7*7+B*2=13*13

49+B*2=169

so now you subtract 169 from 49 and that equals B*2=√120

**SOLUTION:**

we know that

in the right triangle of the figure

Applying the Pythagorean Theorem

therefore

**the answer is the option**

**C) **

## Pythagoras Theorem

The **Pythagoras theorem** which is also referred to as the Pythagorean theorem explains the relationship between the three sides of a right-angled triangle. According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle. Let us learn more about the Pythagoras theorem, its derivations, and equations followed by solved examples on the Pythagoras theorem triangle and squares.

## What is the Pythagoras Theorem?

The Pythagoras theorem states that if a triangle is right-angled (90 degrees), then the square of the hypotenuse is equal to the sum of the squares of the other two sides. Observe the following triangle ABC,** **in which** **we have BC^{2} = AB^{2} + AC^{2}. Here, AB is the base, AC is the altitude (height), and BC is the hypotenuse.

## Pythagorean Theorem Formula

The Pythagoras theorem formula states that in a right triangle ABC, the square of the hypotenuse is equal to the sum of the square of the other two legs. If AB and AC are the sides and BC is the hypotenuse of the triangle, then: BC^{2} = AB^{2} + AC^{2}. In this case, AB is the base, AC is the altitude or the height, and BC is the hypotenuse.

Another way to understand the Pythagorean theorem formula is using the following figure which shows that the area of the square formed by the longest side of the right triangle (the hypotenuse) is equal to the sum of the area of the squares formed by the other two sides of the right triangle.
