Example: 1) The observation deck of the Skylon Tower in Niagara Falls is 166 m above the Niagara River. Alex is in the observation deck; he notices two boats on the water. Alex estimates that, from his position, • the bearing of boat A is 180° at an angle of depression of 40° the bearing of boat B is 250° at an angle of depression of 34° Calculate the distance between the two boats, to the nearest metre.
