Can someone please help with this question! Thank u :) (see photo)

The ratios are identical.

Step-by-step explanation:

Looking at the right angle triangle, taking y° as the reference angle,

Hypotenuse = 15

Opposite side = 9

Adjacent side = 12

To determine Sin y°, we would apply the Sine trigonometric ratio.

Sin θ = opposite side/hypotenuse. Therefore,

Sin y° = 9/15

taking x° as the reference angle,

Hypotenuse = 15

Opposite side = 12

Adjacent side = 9

To determine Cos x°, we would apply the Sine trigonometric ratio.

Cos θ = adjacent side/hypotenuse. Therefore,

Cos x° = 9/15

i believe it's a.

i'm not sure on this one, most likely correct.
