(i) sin2 15 + sin2 75 /cos2 36 +cos2 54
= sin^2(90 - 75) + sin^2 75/cos^2 36 + cos^2(90-36)
= cos^2 75 + sin^2 35/cos^2 36 + sin^2 36
= 1
(2) sin ( 5 + 85) = sin 90 = 1
(3) sec 16 cosec 74 - cot 74 tan 16
= cosec74 cosec74 - cot74 cot74
=cosec^2 (74) - cot^2(74)
= 1
= sin^2(90 - 75) + sin^2 75/cos^2 36 + cos^2(90-36)
= cos^2 75 + sin^2 35/cos^2 36 + sin^2 36
= 1
(2) sin ( 5 + 85) = sin 90 = 1
(3) sec 16 cosec 74 - cot 74 tan 16
= cosec74 cosec74 - cot74 cot74
=cosec^2 (74) - cot^2(74)
= 1
Thank You Faisal bhai For the brainliest.
it's my pleasure
