Answer:
A ) The Equation of the circle (x−10)2+(y−24)2=676
Step-by-step explanation:
step1:-
The equation of the circle whose center is (a,b) and radius r is
![(x-a)^{2} +(y-b)^{2} =r^{2}](https://tex.z-dn.net/?f=%28x-a%29%5E%7B2%7D%20%2B%28y-b%29%5E%7B2%7D%20%3Dr%5E%7B2%7D)
![(x-10)^{2}+(y-24)^{2} =676](https://tex.z-dn.net/?f=%28x-10%29%5E%7B2%7D%2B%28y-24%29%5E%7B2%7D%20%20%3D676)
in this circle equation centre is (g,f) = (10,24)
and formula of radius of a circle is
r = ![\sqrt{g^{2}+f^{2} -c }](https://tex.z-dn.net/?f=%5Csqrt%7Bg%5E%7B2%7D%2Bf%5E%7B2%7D%20-c%20%7D)
Step2:-
The Equation of the circle (x−10)^2+(y−24)^2=676
Answer:

Step-by-step explanation:
1.B, 2. F, 3. E, 4. A, 5. D, 6. C
Remember equal to means solid dot
Answer:
<A = 76°
<B = 63°
<C = 41°
Plug in the value of x
<C = 34 + 7
<C = 41°
Step-by-step explanation:
(sum of ∆)
Solve for x
![63 + 2x + 8 + x + 7 = 180](https://tex.z-dn.net/?f=%2063%20%2B%202x%20%2B%208%20%2B%20x%20%2B%207%20%3D%20180%20)
Add like terms
![78 + 3x = 180](https://tex.z-dn.net/?f=%2078%20%2B%203x%20%3D%20180%20)
Subtract 78 from each side
![78 + 3x - 78 = 180 - 78](https://tex.z-dn.net/?f=%2078%20%2B%203x%20-%2078%20%3D%20180%20-%2078%20)
![3x = 102](https://tex.z-dn.net/?f=%203x%20%3D%20102%20)
Divide both sides by 3
x = 34
<A = 2x + 8
Plug in the value of x
<A = 2(34) + 8 = 76°
<B = 63°
<C = x + 7
Plug in the value of x
<C = 34 + 7
<C = 41°
