Answer:

SAS , ASA, SSS

Step-by-step explanation:

SAS , side A= side A . Angle B= Angle C, side R= side R

ASA, Angle A= Angle A . Side B= side C, Angle R= Angle R

SSS

side A= side A . Side B= side c, side R= side R

Answer:

<h2>They are congruent by SAS postulate.</h2>

Step-by-step explanation:

Choice for this question are

In the image attached, you can observe the pairs of triangles we are talking about. Notice that they are right triangles, which means the congruence postulates we could use are Hypothenuse-Leg, Leg-Leg, Leg-Angle and Hypothenuse Angle, however, this choices are not useful.

We know by given that

$AC \cong AB$ and $RC \cong RB$

We also know that $\angle B \cong \angle C$

So, we have two corresponding sides congruent, and the pair of corresponding angle formed by those sides are also congruent.

Therefore, by Side-Angle-Side

$\triangle ABR \cong \triangle ACR$

So, the right answer is SAS.

First we need to figure out how much gas the car has in its tank so 3/4 of 12 is 9. Now we need to figure out an equation to use to solve this problem.
Let x=distance

30/1.5=x

Multiply 30 and 1.5 by 6 because we have a 9 gallon tank.

180 miles for a 9 gallon tank.

I think the best answer is D. because you can't really go more than you have in your tank. But you can go under and still have enough fuel to fill up.
