Soccer player #1 is 9.3 m from the goal. If she kicks the ball directly into the net, the ball has a displacement labeled A. If, on the other hand, she first kicks it to player #2, who then kicks it into the net, the ball undergoes two successive displacements, Ay and Ax. What are the magnitude and direction of Ax and Ay?
Ax
_____m North--or South--or East-- or West
Ay
_____m North--or South--or East-- or West

There's much info missing to give an accurate answer to this question:

Which direction is the net from #1?

If we assume the direction is due East, or positive x, then we need to know the direction to the other player. If the player is due North, positive y, then we need to know if Ay is greater than the position of player #1 to the North support of the net and does the player kicks directly into the net, Ax.

Also, it is possible that the net is North of East of player #1 and player #2 kicks to the exact same spot that player #1 would have kicked.

I will assume this case, and that there is an angle, th, equal to the arc tangent of Ay/Ax

Then, Ay=sin(th)*9.3
and Ax=cos(th)*9.3
