20 P Hyp 63.1°/64.6) 25m Q d. 1102 Xole R The diagram above (not drawn to scale) shows the angles of elevation of T, the top of a vertical most from the points P and Q from the same side of R on a horizontal plane . P, Q and P lie on a straight line · PQ = 25m, angles TPQ and TQR are 53.1⁰ and 64.6⁰° respectively. :) Show that the length of QT is 100m to the nearest metre. (11) Hence or otherwise calculate the height of the mast.
