Since the equations are not shown, I believe that it could possibly be cos T = 4/17

The equation for the ∠XYT is sin Y=4/17 and cos Y=√273/17.

We need to find the equation for the ∠XYT in terms of sine and cosine.

What is the sine ratio in trigonometry?

The sine ratio in trigonometry is sinθ=Opposite/Hypotenuse.

Now, YT²=XT²+XY²

⇒17²=4²+XY²

⇒XY=√273

Now, sin Y=4/17

cosθ=Adjacent/Hypotenuse

cos Y=√273/17

Therefore, the equation for the ∠XYT is sin Y=4/17 and cos Y=√273/17.
