Answer:
(6, 9 ) and r = 3
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Given
x² + y² - 12x - 18y + 108 = 0
Rearrange the x- terms and the y- terms together and subtract 108 from both sides, that is
x² - 12x + y² - 18y = - 108
To obtain standard form use the method of completing the square
add ( half the coefficient of the x and y terms )² to both sides
x² + 2(- 6)x + 36 + y² + 2(- 9)y + 81 = - 108 + 36 + 81
(x - 6)² + (y - 9)² = 9 ← in standard form
with centre = (6, 9 ) and r = 
= 3
7 2/3 + 8 5/6 = 16 1/2 ( or 32/2 )

Answer:
The value of the variable 'b' is 3 and GH is 9
Step-by-step explanation:
Given:
H is between G and I
Such that G - H - I
To Find:
GH = ?
Solution:
On Substituting HI we get
Substituting 'b' in HI and GI we get
Now, by Line Addition Property we get
Substituting 'HI' and 'GI' we get
The value of the variable 'b' is 3 and GH is 9
