Which proportion can be used to find the missing side length of Triangle JKL?

no idea where that file is.

But all corresponding sides are in the same proportion. So pick two where both are given, then use that same ratio for the unknown ones.

To find the missing side length of Triangle JKL, we can use the concept of similarity. When two triangles are similar, their corresponding sides are in proportion.

Looking at the given diagram, we need to find a proportion that relates the missing side length of Triangle JKL to the known side lengths of the other triangle.

Let's denote the side lengths of Triangle JKL as JK, KL, and JL. And for the other triangle, let's denote the corresponding side lengths as AB, BC, and AC.

To find the proportion, we need to identify sides that are corresponding or in the same position in both triangles. In this case, we can see that side JK corresponds to side AB, KL corresponds to BC, and JL corresponds to AC.

Therefore, we can set up the proportion as follows:

JK / AB = KL / BC = JL / AC

Now, using the given information, we can substitute the known side lengths:

3 / 6 = KL / 12 = 15 / 30

Simplifying this proportion, we see that:

1/2 = KL / 12 = 1/2

Therefore, the proportion that can be used to find the missing side length of Triangle JKL is:

KL / BC = 1/2
