Answer 2

Do you see the large reflex angle AOD ?

Answer 3

Small angle( AOD ) = 2 * (ACD)

There is a property like that. Do you know that?

Answer 4

oh yes, I see now .... so 80 degrees
therefore, 180-80 = 100
100+72 = 172
180-172 = 8

Answer 5

Yep. Spot on!

Answer 13

See, from the same property that we used in our previous question, do you see why that corner over there on the right, would be half of x?

It would be x/2 right? Because the central angle is x. Try to visualize it liek the previous case.

That rule clearly states that the points should just be touching the circle, it does not state, in what way.
