Answer:
∠ACB = ∠DFE
Step-by-step explanation:
In SAS postulate,
S refers to Side.
A refers to Angle.
In the triangles, △ABC and △DEF,
AC = DF ( Side )
CB = FE ( Side )
The additional information required to prove is <u>Angle</u>.
Angle between sides AC and CB in △ABC and Angle between sides CB and FE in △DEF respectively.
Angle between sides AC and CB is ∠ACB.
Angle between sides CB and FE is ∠DFE.
So according to SAS postulate,
∠ACB = ∠DFE
6x2 + 2x2 = 16
Remember that it has 4 sides. That’s the trick in the ?
I think it is 5 because you solve it
The answer is x <span> ≤ 6, i think</span>
