The tree died 3696 years ago because 66x5600=369600/10=3696.
Answer: That seems right. Maybe you didn't simplify. Then, it would be 8/11.
Step-by-step explanation:
Given: We have the given figure through which we can see
LK=16,
KJ=10,
LM=24,
MN=15
To Find: Whether KM || JN and the reasoning behind it.
Solution: Yes, KM || JN because 
Explanation:
For this solution, we use the concept of Similar Triangles.
Now, KM || JN if ΔLKM ~ ΔLJN (i.e., if ΔLKM is similar to ΔLJN).
Now, ∠MLK=∠NLJ
To prove similarity of the two triangles, we have to show that the sides are proportional. In other words, LK:KJ = LM:LN

which is true as both sides simplify to 
Thus, we see that ΔLKM ~ ΔLJN (i.e., if ΔLKM is similar to ΔLJN).
Therefore, KM || JN.
To come to the reasoning, notice that

In other words,

Plot at 9.3
Answer:
The bottom one
Step-by-step explanation:
the lowest dot is on -3 so that's the y-intercept
the other is at 2 x and -1 y
