Answer:

Explanation:
To solve this, all we need to do is draw a triangle.
From the
we can deduce that

From that, we can draw our triangle as we know that tan(x) is the opposite side over the adjacent side. Attached is that triangle. Through the Pythagorean Theorem, we can find that the hypotenuse of this right triangle is

Now all we need to do is take the sin of this triangle, which is the opposite side over the hypotenuse
This gives us the value of
which is our answer.
