If sin y° = s divided by 8. and tan y° = s divided by t., what is the value of cos y°?

step-by-step explanation:

it s given that and .

also, we know that   and , therefore

hypotenuse=8, base=t and perpendicular=s.

now, using trigonometery, we have

substituting the given values, we have

which is the required value of cosy.
