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
1/3 (3x+12)
1/3×3x+1/3×12
x+4
There is a 1/2 chance that he will get at least one of the two features.
There are 3 x 4 = 12 possibilities. There are all 4 colors of each 3 sizes.
All 4 of the medium trucks have one of the features.
For the other 2 sizes, only the red truck will have one of the features.
There are 4 + 2 = 6 possibilities out of 12 for a chance of 6/12 or 1/2.
