Answer:
The answer is 2
Step-by-step explanation:
The hypotenuses of the triangles are different. One is 4 and the other is 5.
Lets use ratios to find the relationship of the hypotenuse and the base.
2.5:5
Turn this into a fraction
2.5/5
Now divide
2.5/5 = 0.5
The base of the triangle is half the length of the hypotenuse.
So 4 is x’s hypotenuse so:
4 x 0.5 = 2
X = 2
Answer with explanation:
Given:
In Δ DEF, ∠3=∠4.
To prove:→ DE=E F
Proof:
1. ∠3=∠4------[Given]
2. →∠1 and ∠ 3 are Supplementary to each other.
(a)⇒∠1 + ∠ 3=180°
→∠2 and ∠ 4 are also Supplementary to each other.
(b)⇒∠2 + ∠ 4=180°
--------------------[Exterior sides in opposite rays]
3. From 1 , a and b
⇒∠ 1 = ∠ 2-------[Two Angles Supplementary to equal Angles are equal to each other]
4. 
If two angles of a Triangle are equal , then side opposite to these angles are equal.
