Answer:
n=13/7
Step-by-step explanation:
2n+4+6*2=-9*2+8(2n+1)
2n+4+12=-18+16n+8
16+18=16n-2n+8
34=14n+8
34-8=14n
26=14n
n=13/7
10*10-2*3/2-4*3/2-2*3/2-2*3/2-5*2-6*2/2-5*2-3*2/2

Answer:
EF is the longest side of △DEF,
DF = 6 cm and
DE = 6 StartRoot 3 EndRoot cm.
Step-by-step explanation:
The angle ∠ EDF = 90° of the right triangle Δ DEF and ∠ DEF = 30° and ∠ EFD = 60°.
The hypotenuse EF is 12 cm.
Now, Sin ∠ EFD = DE/EF
⇒
⇒ DE = 6√3 cm.
Again, Cos ∠EFD = DF/EF
⇒
⇒ DF = 6 cm.
Therefore, EF is the longest side of △DEF, DF = 6 cm and DE = 6 StartRoot 3 EndRoot cm. (Answer)
