Question

रिक्त स्थानों की पूर्ति 0 और 90° के बीच के किसी कोण से करें।
(i) sin 70° = cos (...)
(ii) sin 35° = cos (.. .)
(iii) cos 48° = sin (...)
(iv) cos 70° = sin (...)
(v) cos 50° = sin (...)
(vi) sec 32° = cosec (...)

Answer 1

Answer:

sin 70° = cos 20°

sin 35° = cos55°

cos 48° = sin 42°

cos70° = sin20°

cos 50° = sin 40°

sec 32° = cosec 58°

Step-by-step explanation:

i) cos theta = sin (90 - theta) ; theta = 70°

ii) cos theta = sin (90 - theta) ; theta = 35°

iii) sin theta = cos (90 - theta) ; theta = 48°

iv) sin theta = cos (90 - theta) ; theta = 70°

v) sin theta = cos (90 - theta) ; theta = 50°

vi) cosec theta = sec (90 - theta) ; theta = 32°
