Problem 106 of 7
Use special triangles in the applied context: A path forms a right angle with a fence. A dog runs 8 yards along the path, then turns 45 degrees and runs to a tree. The path to the tree forms a 45-degree angle with the fence.
Using a hint is okay. It just tells the trainer to give you a little more review.

Full solution stays hidden until you ask for it.
1. Identify the special triangle from angles or shape.
2. Match the known side to the ratio.
3. Scale to find the requested context quantity.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
