Answer:
Sinx = 5/13
cosy = 5/13
cosy = sinx ; they both share a proportional relationship
Step-by-step explanation:
From the attached triangle, since the triangle is right angled, we can use trigonometric functions where ;
sinx° = opposite / hypotenuse
From Pythagoras ;
Hypotenuse = √(opposite² + adjacent²)
Hypotenus = √(12² + 5²)
Hypotenus = 13
Sin x° = opposite / hypotenus = 5 / 13
Sin x° = 5/13
Cos y = adjacent / hypotenus = 5 / 13
Hence,
sinx = cosy
Therefore, they both share a proportional relationship.
