Wybierz właściwą odpowiedź spośród podanych. \( \begin{array}{ll}\text { A. } \cos 120^{\circ}+\cos 60^{\circ} & \text { C. } \cos 120^{\circ}-\sin 150^{\circ} \\ \text { B. } \cos 60^{\circ}-\cos 120^{\circ} & \text { D. } \cos 120^{\circ}+\sin 150^{\circ}\end{array} \) A wall is to be supported by a wooden pole. In order for a support pole to keep a wall vertical, the angle of elevation of the pole must be within the range of \( 30-60 \) degrees. If the pole is 8 feet long, determine the distance from the base of the wall to position the pole. Show that: \[ \frac{1}{\sec \theta-1}+\frac{1}{\frac{\sec \theta+1}{\operatorname{cosec}^{2} \theta}}=2 \cos \theta+ \] A construction worker needs to build a ramp for wheelchair access. If the height of the entrance is 3 feet and the ramp must create an angle of \( 30^{\circ} \) with the ground, what is the length of the ramp? e) \( \cot \theta+\tan \theta=2 \csc 2 \theta \)
