The angle of depression from the top of an 8 m tree down to a rabbit is
. If an eagle is perched in the top of the tree, how far does it need to fly to reach the rabbit, to the nearest metre?
The answer is 12m, and I don't even know what this question is trying to visually convey to me.
Hint
Consider that the tree is an isoceles triangle, so one side of the tree is a right triangle. You know the angle $(43.52°)$ and the height $(8$ meters). Try to remember the trigonometric function which relates the hypothenuse and the adjacent side.
I am sure that you can take from here.
