Question

Draw on the image to show how you would figure out the missing side length of the right triangle. Once you are finished, enter the length of the green side length (b) as accurate as you are able. b Length square

Answer 1

`b\text{ = 4.3}`

Here, we want to find the missing side length

As we can see from the image, the respective sides form a right triangle

To find the length of the missing side, we are going to use Pythagoras' theorem

It states that the square of the hypotenuse equals the sum of the squares of the two other sides

Looking at the image, we can see that the side which is the longest is the hypotenuse and it faces the right angle

The measure of this is 8.2

Let us have the measure of the side of the green square as g

Mathematically;

`\begin{gathered} 8.2^2=g^2+7^2 \\ g^2=8.2^2-7^2 \\ g^2\text{ = 18.24} \\ g\text{ = }\sqrt[]{18.24} \\ g\text{ = 4.3 } \end{gathered}`
