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
if a > 0, there are two possible solutions:

the square root of a square is the base in absolute value bars


if a = 0, that means x = 0. anything multiplied by 0 is 0
if a < 0, there are no solutions because anything squared has to be positive
