First a triangle with legs of 8 and 15. Let x be the angle we'll refer to.

By using pythagorean's theorem, we find that the hypotenuse is 17 units

Since this means (notice how the arctangent is gives you an angle)

Now remember and (remember the cosecant and sine function are reciprocals of each other)

So

which also means

So the answer is A)
