Answer:

cosine =  √31/6

Step-by-step explanation:

It is given that,

sine=√5/6

we know that, sine = opposite side/Hypotenuse

To find Adjacent side

Adjacent side = √(Hypotenuse² - opposite side²)

Adjacent side =√(6² - √5² ) = √(36 - 5 ) = √31

To find cosine

cosine = Adjacent side/Hypotenuse

cosine =  √31/6
