f tan x ̊= z /10 and cos x ̊=10/y ,what is the value of sin x°?

sin x° = y/z

sin x° = z/y

sin x° = 10z

sin x° = 10y


*I have no idea what I am doing* with this one.

Answer 1

tangent is opposite/adjacent, so z is opposite and 10 is adjacent.
cosine is adjacent/hypotenuse, so 10 is adjacent and y is hypotenuse.

sine is opposite/hypotenuse, and z is opposite and y is hypotenuse. Therefore,
sin xº = z/y

Answer 2

Thank you so much!
