Capitolo 2, Problema 74
Convert each angle measure to degrees, minutes, and seconds. If applicable, round to the nearest second. 102.3771°
Guida verificata passo dopo passo1
Identify the given angle in decimal degrees: \(102.3771^\circ\).
Separate the whole number part from the decimal part. The whole number part is the degrees: \(102^\circ\).
Convert the decimal part (0.3771) to minutes by multiplying by 60: \(0.3771 \times 60\).
Separate the whole number part of the minutes from the decimal part. The whole number is the minutes.
Convert the remaining decimal part of the minutes to seconds by multiplying by 60: (decimal part of minutes) \(\times 60\). Round to the nearest second if necessary.

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.
Decimal Degrees to Degrees, Minutes, and Seconds Conversion
This concept involves converting an angle expressed in decimal degrees into degrees, minutes, and seconds (D° M' S"). Degrees remain the integer part, minutes are obtained by multiplying the decimal remainder by 60, and seconds come from multiplying the new decimal remainder by 60 again.
