Capitolo 2, Problema 55
Convert each angle measure to decimal degrees. If applicable, round to the nearest thousandth of a degree. 112° 15'
Guida verificata passo dopo passo1
Identify the components of the angle: 112° (degrees) and 15' (minutes). Remember that 1 degree = 60 minutes.
Convert the minutes to decimal degrees by dividing the number of minutes by 60. Use the formula: \(\text{Decimal degrees from minutes} = \frac{\text{minutes}}{60}\).
Calculate the decimal degrees from the minutes: \(\frac{15}{60}\).
Add the decimal degrees obtained from the minutes to the whole degrees to get the total angle in decimal degrees: \(112 + \frac{15}{60}\).
If required, round the final decimal degree value to the nearest thousandth.

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.
Degrees, Minutes, and Seconds (DMS) Notation
Angles can be expressed in degrees (°), minutes ('), and seconds ("), where 1 degree equals 60 minutes and 1 minute equals 60 seconds. This notation is commonly used in navigation and surveying to represent precise angle measures.

Conversion from Minutes to Decimal Degrees
To convert minutes to decimal degrees, divide the number of minutes by 60 since there are 60 minutes in one degree. For example, 15 minutes equals 15/60 = 0.25 degrees, which can then be added to the whole degrees.
