Answer:
300 ft
Step-by-step explanation:
Since the angle of depression is 45°:
- the tower
- the line from the base of the tower to the base of the tree
- the line from the top of the tower to the base of the tree
form an isosceles right angles triangle with angles 45°, 45° and 90°. So the horizontal distance from the tower to the tree is the same as the height of the tower, which is 300 ft.
