Answer:
angle b and c are vertical angles.
We can solve this problem by using the laws of exponents. The laws of exponents state:

=

We can use this law in our situation. The answer here, using the laws of exponents, is

or
5.
B because it’s the only one with a negative and normal number
Answer:
The answer to your question is below
Step-by-step explanation:
- The Standard form of the equation is
(x - h)² + (y - k)² = r²
4.
Center (8, -4) r =
-Substitution
(x - 8)² + (y + 4)² =
²
-Result
(x - 8)² + (y + 4)² = 118
5.
Center (-10, 9) r = 
-Substitution
(x + 10)² + (y - 9)² =
²
-Result
(x + 10)² + (y - 9)² = 37
6.-
Center (-8, 0) r = 6
-Substitution
(x + 8)² + (y - 0)² = (6)²
-Result
(x + 8)² + (y - 0)² = 36
