If you draw a line perp to ZP thru the

midpoint of ZP then any point on that perp line would be A, because Z and P have to be equal distances from any point on the perp. So there isn't just one answer. (There'd be two answers if they told you something like "and the two same-length sides have to have length Q" or something, but I guess they didn't.)
