A person on a bridge sights a boat at an angle of depression of 6 degrees. The bridge is 96 feet above the water. What is the distance between the person and the boat?
We have a right triangle with an opposite side of 96......the hypotenuse is the distance we want
So....the sine function is what we need
So we have
sin (6°) = 96 / D rearrange as
D = 96 / sin (6°) ≈ 918.4 ft
