Ion know. What’s the question
Answer:
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!
Answer:
34 = s
Step-by-step explanation:
To solve for s, add 21 to both sides of the equation.
13 = s - 21
21 + 13 = s - 21 + 21
34 = s
