Help solving?
I don't understand this one either. I got one like it but don't remember how.

If mAB (arc) = 52 degrees and mCD (arc) = 14 degrees, what is the value of x? The figure is not drawn to scale.

x= 33 degrees
x= 38 degrees
x= 59 degrees
x= 66 degrees
(I'll put the figure up in a second)

average the arcs ... this time the angle is inside so the have a positive connotation:

add up the arcs, and divide by 2

|dw:1401825121603:dw|

in all cases, its an average:$$angle=\frac{a+b}{2}$$ just need to keep the sign of the arc in mind
