Answer:
MN = 4
m∠MLN = 42°
Step-by-step explanation:
If ΔMLN is congruent to ΔYZX, then
ML ↔ YZ MN ↔ YX LN ↔ ZX ∠M ↔ ∠Y ∠L ↔ ∠Z ∠N ↔ ∠X
and all those correspondences are congruent when the triangles are congruent

You mean is it an irrational number?
No, it's not!
An irrational number is a number that canNOT be expressed as a fraction, and this number can be easily represented as a fraction: such as this one:
The reflection line is located at y = -x
For point J, x is -2, so y = -(-2), which equals 2.
When it is a reflection across Y, the X values remain the same.
Find the distance of the Y point to the reflection line,
The distance from -1 to 2 is 3 units.
The new point needs to be the same distance from the reflection line.
2 + 3 units = 5.
Point J' would be (-2,5)
