Subtr. 45 from boths ides: x = -25 (answer)
Answer:
3 is what i got so x=3
Step-by-step explanation:
Answer: The abbreviation that supports the conclusion is SAS
Step-by-step explanation:
Given WS=NT
AS=OT
S=T
We have two triangles named WAS and NOT
where we have two sides (WS=NT and AS=OT)
and an angle(S=T) equal
Since the angle is between the two sides
So the postulate that supports is SAS
i.e Side Angle Side
The answer should be C: 12
