Please help! will give brainliest answer if wanted. Which method would you use to prove that the two triangles are congruent?
a. SSS
b. SAS
c. ASA
d. AAS

c.ASA

Step-by-step explanation:

There are two angles that are shown in both triangles and are equal. Then there is a side which is also shown in both triangles, thus we can use ASA to prove that the two triangles are congruent.  

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
