Answer:

First, distribute the -2 to each value in the parentheses.

-2x + 4 = 10

(The 4 is positive because a negative multiplied by a negative is a positive)

Then, subtract 4 from both sides to get rid of it.

-2x = 6

Divide by -2 to get x by itself

x = -3

Which method would you use to prove that the two triangles are congruent?

Alona [7]

Answer:- AAS postulate

Explanation:-

AAS postulate tells that if two angles and a non-included side of a triangle to equal to the two angles and a non-included side of another triangle then the two triangles are said to be congruent.

Given:- One angle and one side of a triangle is equal to the one angle and one side of the other triangle.

We see there is one more pair of equal angles as they are vertically opposite angles . [See the attachment]

⇒ there is a triangle where two angles and a non-included side of a triangle to equal to the two angles and a non-included side of another triangle then the two triangles are said to be congruent.

⇒ The triangles are congruent [ by ASA postulate]
