Answer:
Reasons:
1. Given
2. Given
3. Definition of bisector
4. Reflexive property
5. SAS Congruence
Step-by-step explanation:
This is quite easy to solve. All that you're expected to do is to complete the reason that justifies each statement given in the two-column proof.
Let's complete the proof as follows:
1. Statement:
1. Reason: Given
We know this statement is true because we are given in the question.
2. Statement: FG bisects <DFE
2. Reason: Given
We also know this because we are told so in the question, as shown in the diagram given.
3. Statement: 
3. Reason: Definition of bisector
We know this because an angle bisector divides an angle into two equal halves. Therefore, the definition of bisector justifies why it was stated that 
4. Statement: 
Reason: Reflexive property.
5. Statement: ∆DFG
EFG
5. Reason: SAS Congruence
Two sides (DF and FG) and an included angle (angle 1) of ∆DFG is congruent two corresponding sides (EF and FG) and an included angle (angle 2) of ∆EFG. Therefore, ∆DFG
EFG by the Side-Angle-Side (SAS) Congruence Theorem.
Your answer will be C. false
There is an error in the second step. Before cross multiplying the denominators, LCM of the values should be taken.
Step-by-step explanation:
Step 1; 1 -
=
.
By taking an LCM of x-2 on the LHS, we get
-
=
,
as both terms on the LHS have same denominator, we can add them up,
=
=
.
Step 2; Now we cross multiply the denominators.
(x - 4) × (x + 2) = (x + 1) × (x - 2),
x² - 2x - 8 = x² - x - 2,
(x² - 2x - 8) - (x² - x - 2) = 0.
x² - x² - 2x + x - 8 + 2 = 0,
-x -6 = 0,
x = -6.
By simplifying the given expression, we get x = -6.
