Final answer:
The Moon's angular size is approximately 30 arcminutes and 1800 arcseconds.
Step-by-step explanation:
The Moon's angular size of ½ degree can be converted into arcminutes and arcseconds. There are 60 arcminutes in a degree, so to convert ½ degree into arcminutes we multiply by 60: ½ degree x 60 arcminutes per degree = 30 arcminutes.
Arcminutes can then be further converted into arcseconds. There are 60 arcseconds in an arcminute, so to convert 30 arcminutes into arcseconds we multiply by 60: 30 arcminutes x 60 arcseconds per arcminute = 1800 arcseconds.
Therefore, the Moon's angular size is approximately 30 arcminutes and 1800 arcseconds.
The Moon's angular size is about ½ degree. Since there are 60 arcminutes in a degree, the Moon's angular size in arcminutes is ½ degree times 60, which is 30 arcminutes. Furthermore, since there are 60 arcseconds in an arcminute, the Moon's angular size in arcseconds is 30 arcminutes times 60, yielding 1800 arcseconds.
