Answer 1

To determine which of the measurements have three significant digits, let's analyze each one:

1. 134 meters: This has three significant digits (1, 3, and 4).

2. 56.09 inches: This has four significant digits (5, 6, 0, and 9).

3. 0.52 centimeters: This has two significant digits (5 and 2). The leading zero does not count.

4. 8009 miles: This has four significant digits (8, 0, 0, and 9). The trailing zeros in a whole number without a decimal indicate significance in this case.

The only measurement with three significant digits is 134 meters.
