The correct answer is LN.

If you rotate triangle NLM, it’s easy to see that lines SR and LN are similar.

Two triangles are similar if the ratio of corresponding sides is the same.

If you take the ratio of the following lines:

LN/MN = SR/RT

Where LN = 4
MN = 2
SR = 8
RT = 4

LN/MN = SR/RT

Plug in the values of each side (line):
4/2 = 8/4
2 = 2

Therefore, line LN is proportional to line SR, while line MN is proportional to line RT.

Thus, the correct answer is LN.

Well let's see first we have to divide
132 divided by 12 is 11
Now to check and prove your answer we should use the multiplication.
11 times 12 is 132.
So now you have a solid answer with proof behind it.
If u need a sentence you might want it to go something like this;
Matt brought 11 packs of baseball cards since 132 divided by 12 is 11. 12 times 11 is 132 cards.
