What else would need to be congruent to show that ABC DEF by SAS? E AA. А B OA. BC = EF B. CF OC. ZA ZD D. AC = OF F Given: AC =
serg [7]

The two triangles exist congruent if they contain two congruent corresponding sides and their contained angles exist congruent.

Let $&\overline{A B} \cong \overline{D E} \\ and $&\overline{A C} \cong \overline{D F}

Angle between $\overline{A B}$ and $\overline{A C}$ exists $\angle A$.

Angle between $\overline{D E}$ and $\overline{D F}$ exists $\angle D$.

Therefore, $\triangle A B C \cong \triangle D E F$ by SAS, if $\angle A \cong \angle D$$.

<h3>What is SAS congruence property?</h3>

Given:

$&\overline{A B} \cong \overline{D E} \\ and

$&\overline{A C} \cong \overline{D F}

According to the SAS congruence property, two triangles exist congruent if they contain two congruent corresponding sides and their contained angles exist congruent.

Let $&\overline{A B} \cong \overline{D E} \\ and $&\overline{A C} \cong \overline{D F}

Angle between $\overline{A B}$ and $\overline{A C}$ exists $\angle A$.

Angle between $\overline{D E}$ and $\overline{D F}$ exists $\angle D$.

Therefore, $\triangle A B C \cong \triangle D E F$ by SAS, if $\angle A \cong \angle D$$.

Plss help me do this o-o
Vinvika [58]

Answer:

x=\sqrt6\\y=\sqrt{12}

Step-by-step explanation:

We know that since angles in a triangle add up to 180º, the remaining angle must be 45º.

So the side with length x must be equal to the side with length \sqrt6. That is:

x=\sqrt6

Now, by Pythagoras:

y=\sqrt{(\sqrt6)^2+(\sqrt6)^2}\\=\sqrt{6+6}\\=\sqrt{12}

Is the equation a direct variation?<br> 2y=5x - 1
nikklg [1K]

Answer:

No

Step-by-step explanation: To be direct variation the line must pass through the origin(0,0). This equation has a y-intercept at (0,-1/2) so it does not pass through the origin.

In preparation for the Senior Prom, 8 seniors got together and decided to travel in style and rent a limousine. They investigate
tankabanditka [31]
First we need to calculate the total cost.

The seniors will rent limousine from 8:00 pm till 1:00 am. So total time of rent = 5 hours

Total charges = Charges of first 3 hours + Charges of next 2 hours + Tip
So,
Total charges = $180 + 2($30) +$20 = $260

Thus the total amount the 8 seniors will have to pay is $260. The amount each senior will have to pay is $260/8 = $32.5

Therefore, each student will have to pay $32.5
