Answer:
Given : JKLM is a rectangle.
Prove: JL ≅ MK
Since, by the definition of rectangle all angles of rectangles are right angle.
Thus, In rectangle JKLM,
∠ JML and ∠KLM are right angles.
⇒ ∠ JML ≅ ∠KLM
Since, JM ≅ KL (Opposite sides of rectangles are congruent)
ML ≅ ML ( Reflexive )
Thus, By SAS congruence postulate,
Δ JML ≅ Δ KLM
⇒ JL ≅ MK ( because corresponding parts of congruent triangles are congruent)
Hence proved.

<h2>Explanation:</h2><h2></h2>
Here we need to set a system of two linear equations in two variables. So:
- <em>The sum of digits in a two digit number formed by two digits from 1 to 9 is 8:</em>
Let be those digits, then:
- <em>If 9 is added to a number then both the digits become equal. find the number:</em>
<em />
<em /><em />
<em />
But from eq 1:
Substituting y into the expression 1:
The x-value will be found by hit and trial, so:
- Let x = 1:
We have to reject this solution because digits are different.
- Let x = 2:
We have to reject this solution because digits are different.
- Let x = 3:
<em>Then this is a two digit number formed by two equal digits. </em>
Finally, the number is:
44
