Final answer:

To find the length of GI, we can set up a proportion using the given values. By cross multiplying and simplifying the equation, we can solve for GI. The length of GI is approximately 8.57.

Step-by-step explanation:

In order to find the length of GI, we need to use the concept of proportional triangles. Since FI = 6 and IH = 20, we can set up the proportion:

FI / GI = IH / HI

Substituting the known values, we get:

6 / GI = 20 / (GI + 20)

Cross multiplying and simplifying the equation, we find:

6(GI + 20) = 20(GI)

Expanding and rearranging the equation, we get:

6GI + 120 = 20GI

Subtracting 6GI from both sides, we find:

120 = 14GI

Dividing both sides by 14, we find:

GI = 120 / 14 = 8.57

Therefore, the length of GI is approximately 8.57. Since none of the given answer choices match this value, none of the options provided are correct.
