Answer: D.) SAS

Step-by-step explanation:

SAS congruence postulate says that if two sides and the included angle of a triangle are congruent to corresponding two sides and the included angle of other triangle then we say the two triangles are congruent.

In the given proof , in ΔABD and ΔACD

$\overline{AB}\cong\overline{AC}$ [side] (given)

$\overline{BD}\cong\overline{CD}$ [side] (given)

$\angle{B}=\angle{C}$ [included angle] (Base angles of isosceles triangles are congruent.)

So by SAS congruence postulate ΔABD ≅ ΔACD.

Step-by-step explanation:

AB = AC

BD = CD

<B = <C

So 2 triangles are congruent by SAS

3.3 by 2.5 + 5.7 by 2.5

den301095 [7]

Answer:

22.5

Step-by-step explanation:

Using PEMDAS, we know that for expressions such as this, we're supposed to multiply before we add. This means that it should look something like this: (3.3 x 2.5) + (5.7 x 2.5). When you solve the multiplication first, you get 8.25 + 14.25. Solve, and you get 22.5. This problem can be solved using any basic calculator, or scratch paper!

A machine is used to fill bags with sand. the average weight of a bag filled with sand is 22.3 pounds. Write an absolute value f

frutty [35]

Answer:

$y=f(x)=|x-22.3|$

Step-by-step explanation:

Let the weight of the bag of sand with an unknown weight be given as "x" pounds. Then, the difference between the weight of an average bag of sand which is given to be as 22.3 pounds, is given as $x-22.3$ . Therefore, the absolute value function describing the difference between the weight of an average bag of sand and a bag of sand with an unknown weight will be given as: $|x-22.3|$ .
