Answer 8

Very good.. Now a line from the center of a circle to any TANGENT line forms what?

Answer 9

I'm guessing 90? Because I'm not actually sure.

Answer 10

That is correct tangent lines on a circle will always from a 90 degree angle with a radius drawn from the center to the tangent point because they are perpendicular. I am going to use the letter Z to represent the Center. THus if angle ZCP = 90 and angle ZCB = 52.5 what is angle BCP?
