Question 269919: From a boat on the river below a dam, the angle of elevation to the top of the dam is 27° 58'. If the dam is 2428 feet above the level of the river, how far is the boat from the base of the dam? Answer by drk(1908) (Show Source):
You can put this solution on YOUR website! To solve this we need a tangent function. From above we get
tan(27.966666) = 2428/b
so, b = 2428/tan(27.96666)
b ~ 4572.82 feet
