Problem 60 of 7
Use triangle congruence triangle LMN congruent to triangle RST to find the missing measure ST when MN=2x+1 and ST=9.
Using a hint is okay. It just tells the trainer to give you a little more review.

Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Use the congruence statement to identify the corresponding part.
2. Set corresponding measures equal.
3. Solve if an expression is involved.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Matching noncorresponding vertices.
