Answer:
Proved that DF = FE.
Step-by-step explanation:
See the given diagram attached.
In triangle Δ DEF, we have to prove DF = FE when ∠ 3 = ∠ 4.
The proof is like followings :
1. ∠3 = ∠4, Reason: Given
2. ∠1 and ∠3. Reason: They are supplementary.
∠2 and ∠4. Reason: They are supplementary.
3. ∠1 = ∠2. Reasons: Two Angles Supplementary to Equal Angles are Equal to Each Other.
4. DF = EF. Reason: Opposite sides of equal angles. (Answer)
When you split through fourth into unit fractions you get 5/3 into unit fractions
X=5
Do you need an explanation or is the answer enough?
