Ina circle with centre O, PAX and PBY are the tangents to the circle at points A and B, from an external point P. Q is any point on the circle such that $$\angle QAX = 59^\circ$$ and $$\angle QBY = 72^\circ$$. What is the measure of $$\angle AQB$$?

A

$$31^\circ$$

B

$$72^\circ$$

C

$$49^\circ$$

D

$$59^\circ$$
