Answer:

option C

\(sin(36\°)\ and\ cos(54\°)\)

Step-by-step explanation:

we know that

If

\(\alpha+\beta=90\°\) -------> complementary angles

then

\(sin(\alpha)=cos(\beta)\)

In this problem

the option C

we have that

\(36\°+54\°=90\°\) -------> complementary angles

so

\(sin(36\°)=cos(54\°)\)
