At an altitude of 18,000ft, a helicopter pilot spots the landing pad ahead at an angle of depression of 16 . What is the horizontal distance between the helicopter and the landing pad?(use laws of sines)

Tan 16 = opp / adj      opp is the altitude = 18000

 

tan16 = 18 000 / adj        solve for adj    <=======  the horizontal distance
