Vector A has y-component Ay= +12.0 . A makes an angle of 32.0 degrees counterclockwise from the + y-axis.

What is the x - component of A?

What is the magnitude of A?


How can I do this?

You draw it, and then use trigonometry. (Always draw the problem!) Because you have learned about decomposition about vectors into components, right? This is more or less the same problem.
 


I don't understand the + y - axis

That would be the positive y axis, as in, going upwards, should you choose to define upwards as being positive.

Then, like Hypersphere said, you always need to draw a diagram, and take the proper trigonometric steps to figure out the components and magnitude.
 


Can you locate the y-axis and then tell what part of it is positive? It should be pretty easy to tell. And from there you can figure out where to draw the vector.
