Question about trig ratios

Which trigonometric ratio for a˚ belongs with each value? Enter sin, cos, or tan in each box.

I think I got tan right but if it’s not just let me know, I also need the other two but I got really confused.

Answer 1

Cos a

=opposite/hypotenuse=9/3√13

=3/√13=3√13/13

Sin a

=Adjacent/hyp=6/3√13

=2/√13=2√13/13

Tan a=opposite/adjacent=9/6

=3/2
