What is proving triangles congruent by ASA and AAS
anastassius [24]
So ASA is angle side angle, and that means that if you prove that the side, and the side adjacent to that side and the angle between those two sides are all congruent to another triangle's sides and angle, the triangles are both congruent.
The AAS is angle angle side, or something, so say you have a triangle and you prove that two of its angles are congruent along with a side to another triangle's, then it's AAS. I understand where the confusion might be. I guess it's just a matter of what you state first in your proof?

Two less than three times a number is 28
Alenkinab [10]

Answer:

x = 10

Step-by-step explanation:

Two less than three times a number is 28

Let's break it up.

2 less than: -2

3 times a number: 3x (x is representing a number")

is 28: = 28

So, let's put that together.

Two less than three times a number is 28

3x - 2 = 28

Now, let's solve this.

First, let's isolate the x.

To do this, we must add 2 to each side.

3x - 2 = 28

+2           +2

3x - 2 + 2 = 3x

28 + 2 = 30

We have 3x = 30

Now, we must simplify.

To do this, we must divide each side by 3.

This, in term, will tell us what x equals.

3x = 30

---    ----

3      3

3x/3 = x

30/3 = 10

x = 10

Solve for x.<br>8 + 6x<br>4*+2​
zheka24 [161]

Answer:

x = 0

Step-by-step explanation:

8 + 6x = 4 * 2

If this is the equation then start with multiplying 4 by two and subtracting 8 from both sides

6x = 0

Divide 6 from both sides

x = 0

To test this, insert the value of x which is 0

8 + 6(0) = 4 * 2

Multiply 6 and 0

8 + 0 = 4 * 2

Multiply 4 and 2

8 + 0 = 8

Add

8 = 8

This equation is true as you can see so x is equal to 0.

Hope this helps.
