Answer 1

let theta is a. sina=54
cos(90-a)
=sina
: . cos(90-a)=54

Answer 2

Hey Friend !!! 

I hope your question has some mistakes !!!

Your question should be -

Sin θ = 54° , Then Find Cos ( 90 - θ ) 

...

Your answer is :-

We know that according to Trigonometric Ratios of Complementary Angles ...

Sin θ = Cos ( 90 - θ ) 

So ,


Sin θ = Cos ( 90 - θ )  = 54°

So Your answer is  Cos ( 90 - θ )  = 54°

Hope you would understand !!!
