Answer:cos(53), cos 53 degrees
Step-by-step explanation: sin(angle)= cos(90-angle)
sin(37)=cos(90-37)=cos(53)
C because the relation acts as a function no mater the 2 items

Answer:
Solving the given linear system, we get x = 1 and y = -3.
The solution set is: (1,-3)
Step-by-step explanation:
We need to solve the linear system of equations.

We can write second equation y=x-4 as: 
Let:

Now, Adding equation 1 and 2

So, we get x = 1
Now, put value of x in second equation to find value of y:

So, we get y = -3
Solving the given linear system, we get x = 1 and y = -3.
The solution set is: (1,-3)
