Answers tooken from them, I just wanted to make it easier for you guys to read and find the answers
He made a spelling mistake it’s not 173 acute it’s 73 acute if your worried
I think you are correct.
If the points in order are A,B,C then each point can be the start of a ray, and each ray can go in two directions. But rays from A and C must also include B. So, the rays are
AB (or AC, which is the same)
BA and BC
CB (or CA)
