Here is your answer

Here,

/_BAC= /_DAE (pair of vertically opposite angles )

so,

x+10=2x-10

=> 2x-x= 10+10

=> x= 20

/_ BAC = x+10= 20+10

so,

/_BAC= 30 degrees

Answer:

BAC = 30

Step-by-step explanation:

BAC and CAE are vertical angles, so they are equal

BAC = CAE

x+10 = 2x-10

Subtract x from each side

x-x+10 = 2x-x-10

10 = x-10

Add 10 to each side

10 +10 = x-10+10

20 = x

We want to find BAC

BAC = x+10

= 20+10

BAC = 30

Which of the following is an extraneous solution of the square root of -3x-2=x+2

yarga [219]

Answer:

x=-6 is an extraneous solution

Step-by-step explanation:

we have

$\sqrt{-3x-2} =x+2$

squared both sides

$-3x-2=(x+2)^2$

$-3x-2=x^2+4x+4$

$x^2+7x+6=0$

solve the quadratic equation by graphing

The solution is x=-6 and x=-1

see the attached figure

<u><em>Verify each solution</em></u>

substitute the value of x in the original expression

For x=-6

$\sqrt{-3(-6)-2} =-6+2$

$\sqrt{16} =-4$

$4=-4$ ----> is not true

Is an extraneous solution

For x=-1

$\sqrt{-3(-1)-2} =-1+2$

$\sqrt{1} =1$

$1=1$ ----> is true

Is the solution
