Solve. Round off your answer to the nearest foot. (The picture is not drawn to scale.) A balloon

is 1500 feet above the ground. The angle of depression from the balloon to headquarters is 46°21'. How
far is the headquarters from a point on the ground directly below the balloon (to the nearest foot)?

You obviously have a diagram.

Mark in all the given information.
let the horizontal (adjacent to 46°21') be x ft
What trig ratio involves opposite and adjacent?
