Answer:

x = -6 or x = 6

Step-by-step explanation:

2x^2 - 72 = 0

Divide both sides by 2.

x^2 - 36 = 0

Factor the left side. It is a difference of two squares. The pattern for that is

a^2 - b^2 = (a + b)(a - b). Now we apply that pattern to x^2 - 36 on the left side.

(x + 6)(x - 6) = 0

x + 6 = 0 or x - 6 = 0

x = -6 or x = 6

Using Triangle Congruence Theorems
kodGreya [7K]

There are a total of five theorems congruent triangles. They are summarized as:

  • SAS
  • SSS
  • AAS
  • RHS and
  • ASA.

<h3>What are the definitions of the Theorems of Congruent Triangles?</h3>

SAS - Side Angle Side

According to the SAS rule, two triangles are said to be congruent if any two sides and any angle between the sides of one triangle are equal to the corresponding two sides and angle between the sides of the second triangle.

SSS - Side Side Side Rule

According to the SSS rule, two triangles are said to be congruent if all three sides of one triangle are proportional to the size three sides of the second triangle.

AAS - Angle Angle Side Rule
Angle-Angle-Side is abbreviated as AAS. The triangles are said to be congruent when two angles and a non-included side of one triangle match the comparable angles and sides of another triangle.

ASA - Angle Side Angle rule

According to the ASA rule, two triangles are said to be congruent if any two angles and the side contained between the angles of one triangle are proportional to the size two angles and side included in between angles of the second triangle.

RHS - Right Angle- Hypotenuse side Rule

According to the RHS rule, two right triangles are said to be equivalent if their hypotenuses and one of their sides are identical to those of another right-angled triangle.
