The ones that match are
1 and 5
2 and 6
7 and 3
8 and 4
A number=x
2x/6=42
2x=252 by multiplying both sides by 6
x=126 by dividing both sides by 2 to isolate the variable
3d - e = 7d + e = 5 ⇒ 3d - e = 5
7d + e = 5
3d - e = 5
7d + e = 5 +
-----------------------
10d / = 10
10d = 10
d = 10/10
d = 1
7d + e = 5
7×1 + e = 5
7 + e = 5
e = 5 - 7
e = -2
Answer:
It should be congruent by the AAS congruence theorem
Step-by-step explanation:
The error is in the congruence theorem.
We know that the 2 angles are congruent and one of the sides are congruent. This means that it can either be congruent by ASA or AAS.
It is actually congruent by AAS because it include two angles and the side is opposite of one of the angles.
