It seems like you're asking for help with a problem involving similar triangles, but the information provided is incomplete.

In order to solve this, we need to know which sides of the triangles are corresponding and what the lengths of those sides are.

For example, if triangle ABC is similar to triangle DEF, and we know that side AB corresponds to side DE, BC to EF, and AC to DF, we can set up proportions to find the missing side length.

If AB = 7, BC = 5, AC = 3, DE = 20, EF = ?, and DF = 42, we can set up the proportion:

AB/DE = BC/EF
7/20 = 5/EF

Solving for EF gives us EF = (5*20)/7 = 14.29 (rounded to two decimal places).
