Question

Writing Trigonometric Ratios -

Consider △XYZ
What are the ratios of sine, cosine, and tangent for angle Y?

Answer 1

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!
