Question

Use △XYZ, in which ∠X is a right angle and tanY=815. What is the ratio for sinY? Enter your answer as a fraction in simplest form, like this: 4/25

Answer 1

9999992472/10000000000.

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.
