Problem 209 of 7
Use algebraic expressions in congruence data angle A=5x-10, angle D=90, AB=14, DE=14, angle B=angle E to solve and apply a criterion.
Using a hint is okay. It just tells the trainer to give you a little more review.
Hidden until you reveal it.
set corresponding parts equal and solve before applying criterion.
Hidden until you reveal it.
Expression must represent a corresponding side or angle needed for a valid criterion.
Enter your answer
Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Set corresponding expressions equal.
2. Solve for the variable.
3. Substitute back and apply the appropriate congruence criterion.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Applying criterion before expressions are shown equal.
