Answer:
9999992472/10000000000.
Step-by-step explanation:
If tanY= 815 (which I doubt, shouldn't be so much), XZ= 815 units and XY= 1 units. To find hypotenuse, YZ= √{(815^2) + (1^2)}. Which gives YZ= 815.0006135. So, SinY= opposite by hypotenuse= 815/815.0006135. The answer is wicked, right? I suppose TanY shouldn't be 815 as you stated.
