ok emily this is another simple one. x is the radius of the circle right.

is the 12 the length of the whole line or just up the the point where the line of 9 meets it

u see the kind of dotted line right. that makes ur triangle and the raduis. so the ans for the dotted line is = x

lol what a challenge

It's an easy one, actually. Since the "9" line is right to the "12" line, you know that it also bisects the "12". Which means that you have a right triangle with a long leg of 9, a short leg of 6, and the hypotenuse of that triangle would be the radius of the circle  which also just happens to be what "x" is.

is the entire line 12, or is half the line 12?

 "is the first one actually 15?" Which part of "The answer to the first problem is not 15" is giving you problems? Look at my diagram and all will be clear  IF you THINK about it.

qweqwe is right if the line full length is 12. but if it was the full length the would have centerewd the 12 and not had it ofcentered

yummydumBest ResponseYou've already chosen the best response.0
it goes out from the radius perpendicularly, it cant be offcenter

i still believe the ans is 15

Yes, I see what you're saying, and you may have a valid point. And if the picture is drawn to scale, then your argument is further supported. So if the long leg is 12, then the radius is indeed a nice, neat 15.

Kapt_CrazyBest ResponseYou've already chosen the best response.2
yeah else it would be 10. sumthing

Yeah, a far less than neat 10.82 or so. :)

are there any details aabout the length AB and CD are they given equal in question

I'm gonna go with Kapt_Crazy on this one and say that the radius IS 15 for the first problem, based on the offset "12". But it sure would help if the producers of these diagrams would make things unambiguous for the viewers. On the last problem a leg was found based on the assumption that a particular line was tangent, without the problem giving any clues that it was. And as for the second problem, the 2 chords have hash marks which means they're congruent. If the 2 chords are congruent, then so are the angles they subtend, so x=40

**. If the 2 chords are congruent, then so are the angles they subtend, so x=40 this follows from the two triangles being congruent by sidesideside: (radius, radius, = chord). therefore by corresponding parts of congruent triangles, the central angles are congruent.
