There is something wrong here, or in my interpretation of this
problem. $\angle CGF$ is right, and $\angle CAF$ cannot be right as $AF$
is a cord and not a tangent to the circle with centre $O$. But opposite

Looks like the question has been structured incorrectly then, since it is a scan straight from the actual paper. I will go in and smack my teacher (lol....only joking, will point it out very politely and then glare since i spent so much time trying to work it out....grrrr)

You should check what I wrote, to be sure you agree with its argument.
We can all make mistakes, and so benefit from others checking our work.
