For the 1st question:- that guy moves away from the pole 160 ft. so the adj= 160 and the angle is 62 degrees. Tan(62)= opposite/adj = opp/160 opp=160* tan(62) =300.916 which is approximately equal to 301 he moved upward 6 fts so it should be added to the opposite so the total height is 301+6 = 307 ft
for the 2nd question:- in order to find the 2 other sides we will do the following Sin (30 ) =opposite/hyp opposite= hyp* Sin (30)=12 Sin(30)=6 by the same way Cos(30) = Adj / hyp adj = hyp* Cos(30) = 12 Cos(30)=6 sqrt(3)
