Question b: the longest side is b (the one not labelled) Step by step : A^2+B^2=C^2 8 squared =64 6 squared=36 36+63=100 Square root of 100=10 so the longest side is b
I’m not much help but, I finished this unit a couple months ago, and I think b is the line that’s 6 because it’s across from the 90 degree angle, but my teacher explained it really bad, hope this helped a little.
