Step-by-step explanation:
The standard equation of a circle is 
Center = (h, k)
#1
Center = (0,2)
h = 0
k = 2
r = 5


#2
Center = (-4,-5)
h = -4
k = -5
r = 



#3
Center =(-1,3)
h = -1
k = 3
r = 8



#4
Center: (9,0)
h = 9
k = 0
r = 


Theoretically, the answer will be infinite.
Since one angle of 95 degrees means the other two angles must be acute. You can pick any two real numbers with the sum of 85.
