Final answer:
The length of the missing side is approximately 9.4.
Step-by-step explanation:
To find the length of the missing side, we can use a proportion. Let's call the missing side x. The known sides are A, B, and C. We can set up the proportion as follows: (A / x) = (B / C). Now we can substitute the given values: (34 / x) = (24.4 / 68). Cross-multiplying and solving for x gives us x ≈ 9.44. Rounding to the nearest tenth, the length of the missing side is approximately 9.4.
