C/sinB = 8/sinC
c/sinB=8/0.64
c/sinB=12.5
c=12.5*0.34
c=4.25

8*8+4.25*4.25=a^2
64+18.06=a^2
82.06=a^2
a=sqrt(82.06
a=9.05

The equation of a circle is
sergij07 [2.7K]

Answer:

The answer is

<h3>center = ( - 7 , - 1)</h3><h3>radius = 6</h3>

Step-by-step explanation:

The general equation of a circle is given by

<h3>x² + y² + 2gx + 2fy + c = 0</h3>

where the center of the center of the circle is given by

<h3>( - g , - f)</h3>

From the question the equation is

x² + y² + 14x + 2y + 14 = 0

Comparing with the general equation above we have

2g = 14 2f = 2

g = 7 f = 1 c = 14

So the center of the circle is

<h3>( - 7 , - 1)</h3>

The radius of a circle is given by

r =  \sqrt{ {g}^{2}  +  {f}^{2}  - c}

where

g = 7

f = 1

c = 14

Substitute the values into the above formula

That's

r =  \sqrt{ {7}^{2}  +  {1}^{2} - 14 }  \\ r =  \sqrt{49 + 1 - 14}  \\ r =  \sqrt{36}

we have the final answer as

<h3>radius = 6</h3>

Hope this helps you

One number is 2 more than 3 times another. their sum is 22. find the numbers
scoray [572]
1st number = x, 2nd number = y
Translating the question mathematically it becomes:
x-2 = 3y, or to make it easier: x= 3y+2, x+y= 22

Thus:
(3y + 2) + y = 22 
4y + 2 = 22

Move the 2 on the other side, changing its sign to negative:
4y = 22 - 2
4y = 20

Divide by 4, to obtain only y:
4y : 4 = 20 : 4
y = 5

To obtain x:
x= (3*5) + 2= 15+2 = 17

Verify it: 17+5=22
