A. As you move from left to right, the number of points in the star
remains the same.
B. As you move from right to left the number of points in the tar
increases by 1.
C. As you move from left to right, the number of points in the star
increases by 1.
D. As you move from left to right, the number of points in the star
decreases by 1

cos y = r/q

Step-by-step explanation:

Sine is opposite divided by hypotenuse. Here, since sin y = 7/q, we can say that the opposite side length is 7 and the hypotenuse side length is q.

Tangent is opposite divided by adjacent. Here, since tan y = 7/r, we can say that the opposite side is 7 (just like above with sine) and the adjacent side is r.

Now, we have a triangle with its two legs labelled 7 and r and its hypotenuse labelled q.

Cosine is adjacent over hypotenuse. Because the adjacent side has a length of r and the hypotenuse has length q, we know that cos y must be r/q.

Hope this helps!
