The number of significant figures in each measurement is determined by the number of digits that are known with certainty plus one uncertain digit. In this case:

1. 76.48 cm: 4 significant figures (all digits are known with certainty)

2. 76.47 cm: 4 significant figures (all digits are known with certainty)

3. 76.59 cm: 4 significant figures (all digits are known with certainty)

Therefore, each measurement has 4 significant figures.

1. 76.48 cm: 4 significant figures (all digits are known with certainty)

2. 76.47 cm: 4 significant figures (all digits are known with certainty)

3. 76.59 cm: 4 significant figures (all digits are known with certainty)

Therefore, each measurement has 4 significant figures.
