2. Solve \( 2 \sin \theta+\sqrt{3}=0 \). Give general formula for all solutions. List 8 solutions.

A pylon \( \$ \$ 23.7 \$ \$ \mathrm{~m} \) high casts a shadow \( \$ \$ 46.8 \$ \$ \mathrm{~m} \) long. Determine the angle of elevation of the sun to the nearest tenth of a degree. 23.7 m high casts a shadow 46.8 m long. Determine the angle of elevation of the sun to the nearest tenth of a degree. Show answer

\( \operatorname { coti } x + \operatorname { cosec } x = 11 \)

\( \csc 82.4^{\circ}= \) Blank 1 Express your answer in 3 decimal points.

\( r = \tan \theta \sec \theta \)

3- Sabendo que \( \operatorname{cotag} 40^{\circ}=1,1918 \) e \( \cos 43^{\circ}=0,7314 \), determine. a) \( \operatorname{Cotag} 320^{\circ}= \) b) \( \cos 223^{\circ}= \)
