Question

The angle of elevation of the top P of a vertical tower PQ of height 10 from a point A on the horizontal ground is $45^\circ$. Let R be a point on AQ and from a point B, vertically above R, the angle of elevation of P is $60^\circ$. If $\angle BAQ = 30^\circ$, AB = d and the area of the trapezium PQRB is $\alpha$, then the ordered pair $(d, \alpha)$ is :
