Answer:

40°

Step-by-step explanation:

$m\angle DCB +m\angle ACD = 180\degree$ (Linear pair angles)

$\implies 140\degree +m\angle ACD = 180\degree$

$\implies m\angle ACD = 180\degree-140\degree$

$\implies m\angle ACD = 40\degree$

How do you solve 8/11(n-10)=64

krek1111 [17]

Answer:

n = 98

Step-by-step explanation:

8/11 x (n - 10) = 64

multiply both sides of the equation by 11/8

11/8 x 8/11 x (n-10) = 11/8 x 64

reduce the numbers with greatest common divisor 11

1/8 x 8 (n-10) = 11/8 x 64

n - 10 = 11 x 8

multiply the numbers

n - 10 = 88

so then you add the numbers

n = 88 + 10

n= 98

If A=(-1,-3) and B=(11,-8), what is the length of line ab?

agasfer [191]

Hi!

$A=(-1,-3) \ and \ B=(11,-8)\\\\|AB|=\sqrt{(11-(-1))^2+(-8-(-3))^2}\\\\|AB|=\sqrt{(11+1)^2+(-8+3)^2}\\\\|AB|=\sqrt{12^2+(-5)^2}\\\\|AB|=\sqrt{144+25}\\\\|AB|=\sqrt{169}\longrightarrow\boxed{|AB|=13}$
