Solve the problem.A fire watch tower is to be constructed to provide a view in all directions of a distance of 
Its location is 
east and 
south of the ranger station. Using the ranger station as the origin, write an equation for the circle that bounds the viewing area.
A. (x + 11)2 + (y - 17)2 = 2500 B. (x - 11)2 - (y - 17)2 = 2500 C. (x - 11)2 + (y + 17)2 = 2500 D. (x - 11)2 + (y - 17)2 = 2500
Provide an appropriate response.Solve: x = 8 - 19
