Answer: 
Step-by-step explanation:
For convenience, I labeled some points as shown in the attached picture.
Also, I assume
and
are tangents to the circle.
(reflexive property)
(tangents drawn from a common external point are congruent)
(right angles are congruent)
Therefore, we know
by HL.
Thus, by CPCTC,

This means the measure of minor arc AC is
, and thus 
We need to find out what percentage $912 is of $15 200. The answer is 6%, if I'm understanding the question correctly.
