Answer:
The circle's centre is at the position (3, 5), and it has a radius of 2
Step-by-step explanation:
First let's put it in a useful format by completing the squares:
x² + y² - 6x - 10y + 30 = 0
x² - 6x + y² - 10y = -30
x² - 6x + 9 + y² - 10y + 25 = -30 + 9 + 25
(x - 3)² + (y - 5)² = 4
This tells us that the centre position is (3, 5) and the radius is √4, or 2
Divide 204 to 10.2 or add and then u can get your final answer, you can also multiple.
Answer:
3x =6
x=2
Step-by-step explanation:
5x -2 = 4+2x
Subtract 2x from each side
5x-2x -2 = 4+2x-2x
3x-2 =4
Add 2 to each side
3x-2+2 = 4+2
3x =6
Divide each side by 3
3x/3 = 6/3
x = 2
15 is the answer, I think.
To convert radians to degrees, You replace π with 180 and solve from there.
