The answer to this question is A
<u>Answer:</u> The value of x will be 2.
<u>Step-by-step explanation:</u>
To calculate the value of 'x' or solve for x, we need to isolate x from 8.
In the equation, 8 is in addition with 'x' so for isolating it, we need to apply the reverse operation of addition.
Reverse operation of addition is subtraction.
We need to subtract 8 from both sides of the equation, we get:
By doing this, we get the value of 'x' as 2.
Error done by Alice was that she added 8 and it did not led to the isolation of 'x'.
Answer for the first dropdown box is CAF and EFH
Answer for the second dropdown box is because they are corresponding angles of parallel lines cut by a transversal
Answer for the third dropdown box is transitive property of congruence
------------------------------------------------------------------------------
Explanation:
Angles CAF and EFH are corresponding angles because they are on the bottom side of the parallel lines, and on the right side as well. So they are congruent (due to the lines being parallel).
Since CAF = EFH and EFH = HFD, this means that CAF = HFD
It's similar to saying if x = y and y = z, then x = z. Think of it as a connecting chain. This is the transitive property.
