  -101 feet

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you that the relevant relation is ...

  Tan = Opposite/Adjacent

  Opposite = Adjacent × Tan

  height = (0.5 × 5280 ft) × tan(47°) ≈ 2831 ft

__

The usual relation between estimates and errors is ...

  error = estimate - actual

Then ...

  actual = estimate - error

For the given angle and error, the actual angle is ...

  actual angle = 47° -(-1°) = 48°

  actual height = (2640 ft)·tan(48°) ≈ 2932 ft

Then the change in the height of the mountain due to the error is ...

  2831 ft -2932 ft = -101 ft

The error of -1° in angle estimate creates an error of -101 ft in the height estimate.
