Question 176945: an observation helicopter using a laser devide determines the helicopter is 1800 m from a boat in distress. The helicopter is 1200 m from a rescue boat.the angle formed between the helicopter and the two boats is 35 degrees. how far apart are the boats ? Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! an observation helicopter using a laser devide determines the helicopter is 1800 m from a boat in distress. The helicopter is 1200 m from a rescue boat.the angle formed between the helicopter and the two boats is 35 degrees. how far apart are the boats ?
----------------------
Use the Law of Cosines to get:
d^2 = 1200^2 + 1800^2 - 2*1200*1800*cos(35)
d^2 = 1141263.169
distance = 1068.3 meters
