If sin 43° = m, find the value of
(i) cos 47°
(ii) sec 47°
(iii) tan 47°

Jawaban:

(i) cos 47° = m

(ii) sec 47° = 1/m

(iii) tan 47° = 1

Penjelasan dengan langkah-langkah:

# cos 47° = sin 43° = m

# sec x = 1 / cos x

sec 47° = 1 / cos 47° = 1/m

# tan x = sin x / cos x

tan 47° = sin 47° / cos 47° = m/m = 1
