Look at the figures. How can you prove these triangles are congruent?
Novosadov [1.4K]

Answer:

A. \Delta ABC\cong \Delta DEF by the SAS postulate.

Step-by-step explanation:

We have been two triangles. We are asked to determine the theorem by which both triangles could be proven congruent.

We can see that side DF of triangle DEF is equal to side AC of triangle ABC.

We can also see that side BC of triangle ABC is equal to side EF of triangle DEF.

The including angle between sides AC and BC of triangle ABC is equal to the including angle between sides DF and EF of triangle DEF.

Since both triangles have two sides and their included angles equal, therefore, triangle ABC is congruent to triangle DEF by SAS (Side-Angle-Side) congruence and option A is the correct choice.

Mazyrski [523]

The expression of Mia's height in cm is 5 + x

<h3>How to write an expression of Mia's height in cm?</h3>

The given parameters are

Mia's height = 5 cm taller than her sister

Her sister's height  = x

The parameter "Mia's height = 5 cm taller than her sister" means that

Mia's height = 5 cm + her sister's height

Substitute Her sister's height  = x in Mia's height = 5 cm + her sister's height

Mia's height = 5 cm + x

This means that the expression of Mia's height in cm is 5 + x
