Answer:
(x +4)^2 + (y-2)^2 = 16
Step-by-step explanation:
We can write the equation for a circle with the formula
(x-h)^2 + (y-k)^2 = r^2
Where (h,k) is the center and r is the radius
We know the center is at (-4,2) and the radius is 4
(x- -4)^2 + (y-2)^2 = 4^2
(x +4)^2 + (y-2)^2 = 16
For this problem, we can say that corresponding angles are congruent, or the same, this also means that their angle measures have to be the same. Then, our equations for our angles will be vertical angles, which means that they must equal each other. So we would then write our equation as 3x+20=4x+10 or 4x+10=3x+20. Then, to combine like terms, we will subtract 3x from both sides, resulting in x+10=20. Then we will subtract 10 from both sides, resulting in x=10.

pretty easy
Answer:
The center is (-4,-6) and the radius is 8
Step-by-step explanation:
(x+4)²+(y+6)²=64
The equation of a circle can be written in the form
(x-h)²+(y-k)²=r^2
Where (h,k) is the center and r is the radius
Rewriting the equation
(x - -4)²+(y- -6)²=8^2
The center is (-4,-6) and the radius is 8
