Hello!

Let's review our trigonometric ratios.


Sine= (opposite)/(hypotenuse)


Cosine= (adjacent)/(hypotenuse)


Tangent=(opposite)/(adjacent)

Let's look which lines are opposite, adjacent, and hypotenuse.

Opposite: XZ

Adjacent: YZ

Hypotenuse: XY

Let's plug these into our ratios.


SinY= (XZ)/(XY)


CosY=(YZ)/(XY)


TanY=(XZ)/(YZ)

As you can see, these numbers match answer C.

I hope this helps!
