Step-by-step explanation:
I suspect we don't see the full information for the problem here.
all listed 3 methods are typically used to prove that triangles are congruent (= when turned to have the same orientation, they would simply cover each other completely - no overhanging parts from either triangle).
I guess there is a diagram with 2 triangles and what is known about them.
and since we cannot see them, we cannot tell you which method would apply here.
just remember
SSS means all 3 sides of one triangle are exactly the same as the 3 sides of the other triangle. if you know the lengths of all 3 sides, there is only one triangle you can create. you can only orient it differently.
SAS means two sides and the enclosed angle are the same. again, only one triangle can be created with that information.
ASA means one side and the 2 angles at the end points of that side are known. again, only one triangle can be created with that information.
i would suggest memorizing this

Answer:
x = 5
Step-by-step explanation:
Hello!
For this equation, we start by combining like terms. Since we have two terms with the same variable, we are able to add them together:
3x + 2x + 7 = 32
5x + 7 = 32
As you can see, we added 3x and 2x together.
Now, since we are aiming to get x by itself, we need to subtract 7, from both sides:
5x + 7 = 32
5x = 25
Finally, we divide the 5 attached onto the x by itself, which will leave the x alone on one side:
5x = 25
x = 5
Again, we divided on both sides.
And, there you have it!
x = 5
Hope I helped!

Step-by-step explanation:
8-8x = 12x+4
20x = 4
x = 4/20
x = 1/5
Answer:
a=-1.2
Step-by-step explanation:
5x-10=3x+a=12
let's first find x:
5x-10=12
add 10 to both sides:
5x=22
divide both sides by 5:
x=4.4
now that we know what x is, we can plug it back into the equation to find a:
3*4.4+a=12
first, simplify both sides:
13.2+a=12
then, subtract 13.2 from both sides:
and our answer is: a=-1.2
