Answer:
3) B and C
Step-by-step explanation:
h has to be -4 because two negatives cancel to make a positive, and the equation is 
k would be positive
h is the x value and k is the y value of the center point, so the coordinate of the center would be (-4, 3)
C is correct because 
in the equation, so r would be 
if r was 25, 
would be 625 not 50
Answer:
m∠TRI = 43
Step-by-step explanation:
m∠TRI + m∠IRB = m∠TRB
3x - 5 + x + 27 = 86
3x + x - 5 + 27 = 86 {Combine like terms}
4x + 22 = 86 {Subtract 22 from both sides}
4x = 86 - 22
4x = 64 {Divide both sides by 4}
x = 64/4
x = 16
m∠TRI = 3x - 5
= 3*16 - 5
= 48 - 5
= 43
