Given \cos \theta = -\frac{5}{12}, where \(0^\circ \le \theta \le 360^\circ\),
a) in which quadrant could the terminal arm of \(\theta\) lie?
b) determine all possible primary trigonometric ratios for \(\theta\).
c) evaluate all possible values of \(\theta\) to the nearest degree.
Application
1. A building of height \(h\) is observed from two points, P and Q, that are
105.0 m apart as shown. The angles of elevation at P and Q are 40° and 32°,
respectively. Calculate the height, \(h\), to the nearest tenth of a metre.
