From the top of a tree a bird looks down on a field mouse at an angle of depression of 50 degrees if the field mouse is 40 M from the base of the tree find the vertical distance from the ground to the bird's eye round to the nearest tenth
The tangent function gives the ratio of vertical to horizontal distance in this case. .. vertical distance = (horizontal distance)*tan(angle of depression) .. = (40 m)*tan(50°) .. vertical distance ≈ 47.7 m
