You are almost done!
well, the euation of a circle centered at (h,k) and radius r is
(x-h)²+(y-k)²=r²

so you havve
(x-3)²+(y+5)²=9 (which is correct)
this can be rewritten as
(x-3)²+(y-(-5))²=3²
the center is (3,-5) and the radius is 3

What is the value of x?

Answer:

Option D is correct.

Step-by-step explanation:

We can tell that

$4x + \frac{x}{2} + 2 + \frac{3x-4}{2} = 180$

Now, let's simplify.

=> $4x + 2 + \frac{4x-4}{2} = 180$

=> $4x + 2 + 2x-2 = 180$

=> $4x + 2x = 180$

=> $6x = 180$

=> $x = 30$

Therefore, Option D is correct.

Hoped this helped.
