Answer: 
Step-by-step explanation:
The standard form of a circle is written as such:
Where (h, k) is the center of the circle, and r is the radius.
We know that the center is (-7, 0), so we can plug that into the equation like this: 
The radius is 3 * the square root of 3. To square this, we can multiply 3 squared and the square root of 3 squared:
So, your standard form equation is the following:
Answer:
Step-by-step explanation:
The angle marks mean those angles have the same measure. That means the sides opposite them have the same measure, so ...
2x -24 = x -2
x = 22 . . . . . . . . . add 24-x
The length of BC is x, so is 22.
BC = 22
320% is equal to 3 whole parts and 20% of a part. If one part is 100, then the mixed number would be 3 20/100. However, the problem says to simplify this, so it would be, 3 1/5!
