Answer:[tex]A_x[/tex] = Acos[tex]\theta[/tex]

Explanation:

A vector in this situation have two components

1) The X-component

2) The Y-component

So as we put [tex]cos\theta[/tex] with the x-axis while [tex]sin\theta[/tex] with the y- axis and this case our answer should be

[tex]A_x[/tex] = Acos[tex]\theta[/tex]

I hope this will answer your question,

An image is also provided please have a look at that.

Thank you.

Answer: Ax = Acos(theta)

Therefore, the x component of A: Ax = Acos(theta)

Explanation:

The attached image is a pictorial representation of the question:

From the attached image,

Cos(theta) = adjacent/hypothenus

Cos(theta) = Ax/A

Making Ax the subject of formula,

Ax = Acos(theta)

Therefore, the x component of A: Ax = Acos(theta)
