Question

Ubah ukuran sudut-sudut berikut ke dalam derajat
a. 11°3'8''
b. 56°6'9''
c. 78°4'1''​

Answer 1

Penjelasan dengan langkah-langkah:

1" = 1/60' , 1' = 1/60°

a) 21°3'8'' = 21°3'(8/60)'

= 21°3'0,13' = 21°3,13'

=21°(3,13/160)°

= 21°0,052°=21,052°

b) 56°6'9''= 56°6'(9/60)'

= 56°6'0,15'

= 56°6,15'

= 56°(6,15/60)°

= 56°0,1025°

= 56,1025°

c) 78°4'11''= 78°4'(11/60)°

= 78°4'0,183'=78°4,183'

= 78°(4,183/60)°

= 78°0,0697°

= 78, 0697 °
