Answer:
as following
Step-by-step explanation:

B) Line HI and FI are congruent
because they are both the radius of the circles and their central angles are also congruent.
Because multiply of these two number get you -32, one of these number must be negative.
And because sum of them are positive, positive number must be larger than that negative number (without minus sign)
So list of possible answers are:
-1, 32; -2, 16; -4, 8
And we can see that
-4+8 = 4
So these two numbers are 8 and -4.
Answer:
option (4)
Step-by-step explanation:
Calculate the length using the distance formula
d = 
with (x₁, y₁ ) = A(2, 2) and (x₂, y₂ ) = B(- 6, 4)
AB = 
=
