hi!
its not a function since it has a =5
this is an equation
There is only 1 solution for the length of BC.
We can calculate it using Pythagorean theorem.
We can conclude that triangle's hypotenuse is AC.
![AC^2=AB^2+BC^2](https://tex.z-dn.net/?f=AC%5E2%3DAB%5E2%2BBC%5E2)
If that is the case we are looking for a side BC.
![BC=\sqrt{AC^2-AB^2}](https://tex.z-dn.net/?f=BC%3D%5Csqrt%7BAC%5E2-AB%5E2%7D)
Now put in the data.
![BC=\sqrt{21^2-13^2}=\sqrt{272}=\sqrt{272}\approx\boxed{16.49}](https://tex.z-dn.net/?f=BC%3D%5Csqrt%7B21%5E2-13%5E2%7D%3D%5Csqrt%7B272%7D%3D%5Csqrt%7B272%7D%5Capprox%5Cboxed%7B16.49%7D)
Hope this helps.
