Are you familiar with Pythagoras Theorem?

ffasinger · Answer

yes but this is not the pythagoren therom this is distance formula

fortytherapper · Answer

Oh, Pythagoras cam be used too. I personally find it easier since point A is at the origin.
We can also do distance formula if you like

ffasinger · Answer

ok lol

fortytherapper · Answer

Pythagoras:

Since A is at the origin, we just need point B. Point B makes 2 sides: 8 and 2

8^2 + 2^2 = ?

After that we can take the root of that to find the answer. Lemme know what you get
