Answer:

Angle D is equal to 80.

Step-by-step explanation:

We know that the sides are congruent and that angle ACB is congruent to angle ECD by the vertical angles theorem.

Triangles' angles always add up to 180.

180 - 70 - 30 = 80

angle D is equal to 80.

144+64= 178

\sqrt{178  }  = 13.3

a^2+b^2= c^2

Whenever finding a missing length use the formula up above :

a^2+b^2= c^2

a^2-b^2= c^2

144-64= 80

\sqrt{80}  =  \sqrt{16 }  \times  \sqrt{5}  = 4 \sqrt{5}  = 8.9

Answers are 13.3 and 8.9

Which procedure justifies whether Negative 3 x (5 minus 4) + 3 (x minus 6) is equivalent to Negative 12 x minus 6? The expressio
BlackZzzverrR [31]

Answer:

  The expressions are not equivalent because Negative 3 (2) (5 minus 4) + 3 (2 minus 6) = negative 18 and Negative 12 (2) minus 6 = negative 30

Step-by-step explanation:

Apparently, we're trying to see if ...

  -3(x)(5 -4) + 3(x -6) = -12(x) -6

by evaluating the expressions for x=2:

  -3(2)(5-4) +3(2 -6) ?= -12(2) -6

  -6 -12 ?= -24 -6

  -18 ≠ -30 . . . . . . . . . shows expressions are not equivalent

__

This demonstration matches the one in the first choice:

The expressions are not equivalent because Negative 3 (2) (5 minus 4) + 3 (2 minus 6) = negative 18 and Negative 12 (2) minus 6 = negative 30

Whats the correct answer?
GarryVolchara [31]

Answer:

Actually the answer is "A"

this is a very strange way to present a problem...

this issue her is that (x^{a}) ^{b}  = x^{a*b}

so you need 1/3 * 3 in the answer... none of them have 1/3 * 3

BUT !!!!! 1/3 + 1/3 + 1/3  is the same as  1/3 * 3 So "A" is the solution
