Answer:

${x}^{2} - 2x - 3 \\ = (x - 3)(x + 1) \\ when \: y = 2 \\ x = 1 \\ vertex \: is \: (1, \: 2)$

${x}^{2} = - 625 \\ x = \sqrt{ - 625} \\ x = \sqrt{625} \times \sqrt{ - 1} \\ x = 25 \times \sqrt{ {i}^{2} } \\ x = 25 \times i \\ x = 25i$

What is the missing justification?

frozen [14]

Answer:

Option A is correct.

The missing justification is: Transitive property

Step-by-step explanation:

Given: $\angle A \cong \angle B$ , $\angle C \cong \angle B$

Symmetric property of equality states the if for all real values of x , y

if x =y then, y =x.

Then, by symmetric property of equality:

we can write $\angle C \cong \angle B$ as

$\angle B \cong \angle C$

Transitive property of equality states that if we have the two things that are equal to each other and the second thing is equal to a third thing.

i.e, if a =b and b =c

then a =c

By transitive property of equality:

if $\angle A \cong \angle B$ and $\angle B \cong \angle C$

then;

$\angle A \cong \angle C$ ......[1]

Congruent angle states that the angles have exact the same measure

Therefore, by definition of congruent angles in [1] we have;

$m\angle A = m \angle C$
