    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 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

    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.

    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 side-side-side: (radius, radius, = chord). therefore by corresponding parts of congruent triangles, the central angles are congruent.
