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)
