range
Step-by-step explanation:
*JUST AND EDUCATED GUESS* but id say range 
 
        
             
        
        
        
4.5 hrs because 162.50-50 = 112.50 
112.50/25= 4.5
        
             
        
        
        
Answer:
Option A. (-1, 0)
Step-by-step explanation:
In the figure attached,
Circle O is a unit circle (having radius r = 1 unit)
If a point A with central angles = θ, is lying on the circle then the coordinates of the point A will be,
x = r.cosθ 
x = 1.cosθ = cosθ
and y = r.sinθ 
y = 1.sinθ = sinθ
Therefore, coordinates representing the point A will be (cosθ, sinθ).
As per question the given point A is lying at P (a point having central angle θ = 180°)
Coordinates of point P will be 
(x', y') → (cos180°, sin180°)
         → (-1, 0)
Therefore, Option A will be the answer.
