Question

if sin theta is equal to a/b,find the values of cos 90-theta and cosec theta​

Answer 1

Answer:

it is the right answer

sin (90-0)+cos egupqualtu 2 cos (90-0)

2 cos0 egupqualtu 2sin 0 1 by 2

We know that cosec 20 egupqualtu 1 - cot 0 cosec0 egupqualtu 1+ cot20 cosec0 egupqualtu 1+1 by 2 egupqualtu 3 by 2

Therefore,Answer is 3 by 2
