Answer:
sin x and cos y = 4:5
Step-by-step explanation:
In given right angle triangle.
Relation between sin x and cos y
Using trigonometry formula:


For sin x , Opposite = 16 and Hypotenuse = 20

For cos y , Base = 16 and Hypotenuse = 20


Ratio of sin x and cos y = 4:5
Hence, The sin x and cos y are equal.
