To calculate the percent error, we'll use the formula:
Percent Error = (|Measured Value - Actual Value| / Actual Value) * 100
In this case, the measured value is 28° and the actual value is 32°.
|28 - 32| = 4
Percent Error = (4 / 32) * 100
Percent Error = 12.5%
Therefore, the percent error for Anthony's original measurement is 12.5%.
