Which of the following proportions can be used to find the value of n?

B)

Step-by-step explanation:

The side "ML" is similar to the side "IH", as shown by their position and the small line going through them. If we create a ratio of these sides since they are similar, we get 15/5.

The format of this ratio is (side on big trapezoid)/(side on small trapezoid).

Now, we substitute "GH" in the correct spot now that we have established the format for our ratios.

since "GH" is on the small trapezoid, we get a ratio of

(side on big trapezoid)/11.

So if we set both of our ratios equal to one another now, this is what we get:

which matches choice B.

the answer is:

mean: 6

mad: 2.14
