Answer:

option C

[tex]sin(36\°)\ and\ cos(54\°)[/tex]

Step-by-step explanation:

we know that

If

[tex]\alpha+\beta=90\°[/tex] -------> complementary angles

then

[tex]sin(\alpha)=cos(\beta)[/tex]

In this problem

the option C

we have that

[tex]36\°+54\°=90\°[/tex] -------> complementary angles

so

[tex]sin(36\°)=cos(54\°)[/tex]
