b.) 20° 14' 15" - 10° 56' 45" = ...



​

Penjelasan dengan langkah-langkah:

a.)

20° 14' 15" + 15° 56' 47" = 35° 70' (62")

= 35° 70' (60" + 2")

= 35° 70' + 1' 2"

= 35° (71') 2"

= 35° (60' + 11') 2"

= 35° + 1° 11' 2"

= 36° 11' 2"

b.)

(20°) (14') 15" - 10° 56' 45"

= (19° + 1°) (13' + 1') 15" - 10° 56' 45"

= 19° (60' + 13') (60" + 15") - 10° 56' 45"

= 19° 73' 75" - 10° 56' 45"

= 9° 17' 30"

semoga membantu ya
