1. By definition, you have:
Sin(α)=Opposite/Hypotenuse
2. Then, SinA is:
SinA=BC/AC
A is the angle in the vertice "A".
BC is the opposite leg to the the angle A.
AC is the hypotenuse of the triangle.
3. By definition, you have:
Cosα=Adjacent/Hypotenuse
4. Then, CosC is:
CosC=BC/AC
C is the angle at the vertice "C".
BC is the adjacent leg to the angle C.
AC is the hypotenuse.
5. Therefore, the answer is the last option:
The equivalent to SinA is CosC

I just had this question on a recap quiz I was working on I hope this helps
Answer:
The inverse is
(x) = 
Step-by-step explanation:
(By the way,
(x) is f negative one of x, like f(x), but inverse)
f(x) =
- 4 is the same as y =
- 4
y =
- 4 start with the equation.
x =
- 4 switch x and y.
x + 4 =
add 4 to both sides.
= y square both sides.
(x) =
change y to the inverse f(x) format.
