Problem 26 of 7
Use the side-splitter theorem to find the missing segment from In triangle ABC, DE is parallel to BC. AD=15, DB=x, AE=10, EC=6.
Using a hint is okay. It just tells the trainer to give you a little more review.
Hidden until you reveal it.
set up proportions from parallel segment.
Hidden until you reveal it.
Parallel segment must split two sides of a triangle proportionally.
Enter your answer
Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Identify the two split sides cut by the parallel segment.
2. Set the ratios of corresponding parts equal.
3. Solve for the missing segment.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Using whole side ratios when the theorem asks for split parts unless converted consistently.
