Answer:

Step-by-step explanation:

because the small triangle at the top is isoscel and has the base angles BDE and BED = (180 -48)/2 =66

angle BDE is congruent to DAC = 66, because 2 || BE and AC are cut by transversal BA

angle ADC = 180 -50 -66 = 64

What is the solution to inequality of[9n-9]+10=7

Brilliant_brown [7]

Answer:

n = 2/3

Step-by-step explanation:

[9n-9]+10=7

Subtract 10 from each side

9n -9+10-10 =7-10

9n -9 = -3

Add 9 to each side

9n -9+9 = -3+9

9n = 6

Divide by 9

9n/9 = 6/9

n = 2/3

Find the value of a and b if root3-1/root3+1+ root3+1/root3-1=a+root3 b

Digiron [165]

Answer:

a=4 and b = 0

Step-by-step explanation:

Given : $\dfrac{\sqrt 3 -1}{\sqrt 3+1}+\dfrac{\sqrt 3+1}{\sqrt 3-1}=a+\sqrt 3 b$

To find, The value of a and b

Solution,

Solving LHS of the given equation,

$\dfrac{(\sqrt 3-1)^2+(\sqrt3+1)^2}{(\sqrt 3+1)(\sqrt 3-1)}=a+\sqrt 3 b$

Since,

$(a-b)^2=a^2+b^2-2ab\\\\(a+b)^2=a^2+b^2+2ab\\\\(a-b)(a+b)=a^2+b^2$

So,

$\dfrac{3+1-2\sqrt 3+3+1+2\sqrt 3}{3-1}=a+\sqrt 3 b\\\\4=a+\sqrt 3 b$

$4+0=a+\sqrt 3 b$

On comparing we get :

a = 4 and b = 0
