(b) What is the longest distance from C to the wheel?

Answer 1

If you split it into triangles you can figure out everything with sines and cosines from there. I can help you out more if you need it.

Answer 2

well, actually that's not correct. I have done it.

Answer 3

But thank you so much:)

Answer 4

x is the longest distance from C, but yeah I think you got it, it's really all the pythagorean theorem, I'm tired.
