Answer: The answer is ∠DEG.
Step-by-step explanation: We are given a diagram in which a car is on the road and a helicopter is in the air. We are to find the angle of depression from the figure.
The angle of depression is defined as the angle from the horizontal downward to an object. The line of sight of an observer would be below the horizontal.
Here, helicopter is the observer and car is the object, so the angle of depression will be the angle through which the helicopter is looking at the car, i.e., ∠DEG.
Thus, the answer is ∠DEG.
