Question

please tell the whole method​

Answer 1

Answer:

1,1,1

Step-by-step explanation:

we have sin(90-x)=cos(x)..[1]

tan(90-x)=cot(x)…..[2]

cosec(90-x)=sec(x)…..[3]

of we use [1] in (i) then we get that sin 72 = cos 18

=1

of we use [2] in (ii) then we get that tan 41 = cot 49

=1

of we use [1] in (i) then we get that cosec 17 30 = sec 72 30

=1
