The second pair of ribs or the True ribs
Yes, except that the answer would be an angle whose measure is negative. Such angles are quite useful in trigonometry.
The answer depends on what angle B is and which angle is 108. And since you have not bothered to share that crucial bit of information, I cannot provide a more useful answer.
Such is called an exterior angle. A useful theorem is that an exterior angle is equal to the sum of its non adjacent interior angles.
Yes. Sometimes in mathematics, it is useful to have negative angles. You can increase or decrease an angle by 360 degrees (or 2*pi radians) without changing the characteristics of the angle. Thus, for example, an angle of 30 degrees is equivalent to an angle of -330 degrees.
