6.1 COMPLETE: In ∆ABC b2 = … + … – …
6.2 In the diagram below, PQ is a straight line 1 500 m long. RS is a vertical tower
158 m high with P, Q and S points in the same horizontal plane. The angles of
elevation of R from P and Q are 25° and θ. SP̂Q = 30°.
6.2.1 Determine the length of PS. (3)
6.2.2 Determine the length of SQ. (3)
6.2.3 Hence, find the value of θ. (3)
6.2.4 Determine the area of ΔSPQ. (4)
