To find out how much taller the second pole is than the first pole, you can subtract the height of the first pole from the height of the second pole.
Height of the second pole: 2.172 m
Height of the first pole: 1.83 m
Calculation:
2.172 m - 1.83 m = 0.342 m
The second pole is 0.342 meters taller than the first pole.
