Answer:
c) 12/15 = 4/5
Step-by-step explanation:
imagine we mirror the triangle up, so that Z is on top.
then you can clearly see that 6 is cos(X) times r (and r is then 7.5).
XY is sin(X)×7.5
and again, 7.5 is r (the line making the X angle).
so, the cosine ratio of X is
6 = cos(X)×7.5
cos(X) = 6/7.5 or then 12/15. or simplified 4/5.

Step-by-step explanation:
I didn't know if you wanted the entire answer, so I just gave it anyway.
Here is the graph! I hope this helps!
The results of the composite functions are:
<h3>What are composite functions?</h3>
Composite functions are functions that are obtained by combining two or more functions together
Assume that:
Then the computation of the composite functions are as follows:
<h3>Function (f * g)(x)</h3>



<h3>Function f(g(x))</h3>
We have: 
This gives

So, we have:


<h3>Function g(f(x))</h3>
We have: 
This gives

So, we have:
