We will use trigonometric identities to solve this. I will use θ (theta) for the angle.
First of all, we know that cotθ = 1/tanθ. This is a trigonometric identity.
We can replace cotθ in the expression with 1/tanθ.

Simplify: 1/tanθ * tanθ = tanθ/tanθ = 1
So now, we have:

Next, we also know that secθ = 1/cosθ. This is another trigonometric identity.
We can replace secθ with 1/cosθ in our expression.

Simplify:

Our third trigonometric identity that we will use is tanθ = sinθ/cosθ.
We can replace sinθ/cosθ with tanθ.
Now we have as our final answer:

Hope this helps!
Answer:
4x - 6
Step-by-step explanation:
2 × 2x = 4x
2 × -3 = -6
4x -6
The answer could be either C or D but i am leaning towards D because its saying the Residual value which is the left over from the payment. so that's the money that is left over so she still has to pay for it. the answer is D. $40,320
