Question

A bird at the top of a tree looks down on a field mouse at an angle of depression of 65°. If the field mouse is 30 meters from the base of the tree, find the vertical distance from the ground to the bird’s eyes. Round the answer to the nearest tenth.

Answer 1

Review your basic trig functions.
As always, draw a diagram.
If the distance is x,

tan65° = x/30

Answer 2

so it is 30/tan65 degress plug it in a claculator and you should get 13.9 which equals 14.
