Answer:
![42](https://tex.z-dn.net/?f=42)
Step-by-step explanation:
Remember, ![a^{2} + b^{2} =c^{2}](https://tex.z-dn.net/?f=a%5E%7B2%7D%20%2B%20b%5E%7B2%7D%20%3Dc%5E%7B2%7D)
This time, it's ![56^{2}+b^{2}=70^{2}](https://tex.z-dn.net/?f=56%5E%7B2%7D%2Bb%5E%7B2%7D%3D70%5E%7B2%7D)
=
of ![1764=42](https://tex.z-dn.net/?f=1764%3D42)
