Using ruler and a pair of compasses only,

(a) construct a quadrilateral PXYQ such that /PX/ = 9.9 cm, /QX/ = 10.2 cm, < QPZ = 75°, /QY/ = 10.4 cm and PQ // XY. 

(b) Construct the (i) locus \(l_{1}\) of points equidistant from X and Y ; (ii) locus \(l_{2}\) of points equidistant from QY and YX.

(c) Locate M, the point of intersection of \(l_{1}\) and \(l_{2}\).

(d) Measure /PM/.
