Answer 2

Step-by-step explanation:

(I)

sin 18°/ cos 72° = sin 18°/sin 18° = 1

(2)

tan 26°/cot 64° = tan 26° /tan 26° = 1

(3)

cos 48° - sin 42°

sin 42° - sin 42° = 0

(4)

cosec 31° - sec 59°

sec 59° - sec 59°

= 0

Identities used :

tan ∅ = cot (90-∅)

sin ∅= cos (90-∅)

cosec ∅ = sec (90-∅)
