To determine which of the given measurements has three significant digits, we need to analyze each option:
- 134 meters - This has three significant digits (1, 3, and 4).
- 56.09 inches - This has four significant digits (5, 6, 0, and 9).
- 0.52 centimeters - This has two significant digits (5 and 2). The leading zero does not count as significant.
- 8009 miles - This has four significant digits (8, 0, 0, and 9), as all non-zero numbers and captive zeros (zeros between significant numbers) are counted.
Based on this analysis, the measurement with three significant digits is 134 meters.
