Answer:
The correct option is 1.
Step-by-step explanation:
The angle of elevation is the angle formed by the line of sight and the horizontal plane for an object above the horizontal.
The angle of depression is the angle formed by the line of sight and the horizontal plane for an object below the horizontal.
Since the angle 4 is the angle between the line of sight and the ground for an object above the horizontal, therefore angle 4 is the angle of elevation from the person to the radar tower.
1. "Angle 4 is the angle of elevation from the person to the radar tower."
This statement is true.
2. "Angle 4 is the angle of depression from the radar tower to the person".
This statement is is false.
3. "Angle 4 is the angle of depression from the person to the radar tower".
This statement is false.
4. "Angle 4 is the angle of elevation from the radar tower to the person".
This statement is false.
