Problem 63 of 7
Explain why trig ratios depend only on angle measure in right triangles with a common acute angle vertex.
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. Show right triangles with same acute angle are similar by AA.
2. Use corresponding side proportionality.
3. Conclude the side ratios depend only on the angle.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Saying ratios depend on absolute side length.
