Vector A is in the direction 34.0 degrees clockwise from the -y axis. The x-component of vector A is Ax = - 16.0m

What is the y-component of vector A?

Im not sure how to solve it since the magnitude is not known. CI drew a picture of how i think its suppose to be.

Can someone help me set it up and how they got that answer?

I think since the hypotenuse is not known i use tan somehow.

Thank you
