3.) Lighthouse B is 6.56 miles directly east of lighthouse A. A ship at O observes that A is due north and that the bearing of OB is N 46 10' E. How far is he ship from A? From B?
4.) An airplane is 115 miles due east of radio station A. A second radio station is 136 miles due north of A. What are the distance and bearing of the second radio station from the airplane?
5.)Because of a certain wind, a boat sails 4728 feet in the direction S 47 degrees 29 seconds W. How far south has it gone? How far west has it gone?
Please help me on this. Thank You Guyz!

trig !! #3. Θ = 46° 10 '....OA = 6.56 cot Θ , OB = 6.56 sec Θ
#4.bearing is N arctan 115/136 W......distance is 115 arctan 115/136
#5 . 4728 cos 47°29 '............DRAW the figures
#4.bearing is N arctan 115/136 W......distance is 115 arctan 115/136
