Let's find the length of the hypotenuse CB.
For that, we have the triangle:

The legs are CA and AB
The hypotenuse is CB
Counting the length of CA and AB , we can write:
CA = 5 units
AB = 3 units
Thus, we can put into formula given to find hypotenuse:
![\begin{gathered} \text{hypotenuse}^2=CA^2+AB^2 \\ \text{hypotenuse}^2=5^2+3^2 \\ \text{hypotenuse}^2=25+9 \\ \text{hypotenuse}^2=34 \\ \text{hypotenuse}=\sqrt[]{34} \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/i18uunakbjn8x9e8ahrb0t9vzwjh6bajw0.png)
