We will have the following:
*First. We determine a new point that can be used to complete the rigth triangle; we are given the points:
![\begin{cases}(6,-5) \\ \\ (-3,3)\end{cases}](https://img.qammunity.org/2023/formulas/mathematics/college/n6y55w9h4dqkr27d84bz6gtuo2wu3dsgqe.png)
So, a point we could use to form a rigth triangle could be:
![(-3,-5)](https://img.qammunity.org/2023/formulas/mathematics/college/3uj8riefbtgz4zuk410jsa2ninrdfm4ql1.png)
And we would have the following triangle:
*Second: We determine the distances:
**Distance on the horizontal axis would be 9 units.
**Distance on the vertical axis would be 8 units.
*Third: We determine the distance betweem the two original points:
![h=\sqrt[]{9^2+8^2}\Rightarrow h=\sqrt[]{145}](https://img.qammunity.org/2023/formulas/mathematics/college/sm9gwv5ebi3kuiuz4zo1izi0ypoudhbnkc.png)
![\Rightarrow h=12.04159458\ldots\Rightarrow h\approx12](https://img.qammunity.org/2023/formulas/mathematics/college/5qr91lu8mcn1doy7shp2hckwk6byhraf4c.png)
So, the distance between the two original points is approximately 12 units.
