Answer 1

Ответ:

Объяснение:

1)5° 48' + 7° 35'=12° 83'=13° 23'    (т.к 83'-60' =1° 23')

2)32° 17' - 8° 45' =31° 77' - 8° 45' =23° 32'

Answer 2

To perform the calculations, we'll work with degrees and minutes separately.

1. Addition: 5°48' + 7°35'

For degrees, we add 5° + 7°, which equals 12°. For minutes, we add 48' + 35', which equals 83'. However, since there are 60 minutes in a degree, we can convert 83' into degrees and minutes. Dividing 83' by 60, we get 1°23'.

Therefore, 5°48' + 7°35' is equal to 12°1' (or 12 degrees and 1 minute).

2. Subtraction: 32°17' - 8°45'

For degrees, we subtract 8° from 32°, which equals 24°. For minutes, we subtract 45' from 17'. Since 45' is greater than 17', we need to borrow 1 degree, which gives us 16' + 60' - 45' = 31'.

Therefore, 32°17' - 8°45' is equal to 24°31' (or 24 degrees and 31 minutes).
