Answer:
SAS
Step-by-step explanation:
The triangles are similar by SAS. Two side lengths are given, and we know that vertical angles are congruent.
It is not SSS because we do not know the side lengths of FG and BC.
It is not AA because we do not know two angle measurements.
X=-1
i think that’s what it is
Answer:
x = 3
Step-by-step explanation:
5(2 - x) = 7x - 26
Distribute;
10 - 5x = 7x - 26
Add 5x to both sides;
10 = 12x - 26
Add 26 to both sides;
36 = 12x
Divide both sides by 12;
x = 3
I think your answer is 78 = x -2
For #12, they are vertical angles so 4x=84 degrees. Therefore you take 84 and decide by 4 and you get what x is (it’s 21)
