Answer: Option 'C' is correct.
Step-by-step explanation:
Since we have given that
Two measures of arc are given by
PR = (x+5), and SQ = (x-5).
By intersecting chords theorem, the measure of angle is half of the sum of the measures of arcs.

And ∠A and ∠B are linear pair.
so, it becomes,

Hence, Option 'C' is correct.
