Answer:

Step-by-step 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.
D. would be the right answer mate
21/25 is already a fraction and if you wanted it to be simplified, its already simplified to be 21/25.
Sure, here are what I got for those 2 questions:
16.
No, the Rockets' ratio was 1:3 whereas the Turbo's was 4:9.
17.
They make 33.3333% of free throws, so if they attempted 12, they would make 4 because 1/3 x 12 = 4.
