Finding the coordinates of a point

I am given a point P(x1,y1). I have to find the coordinates of a point at

a distance say DIS from it. The only thing we are given is that this

point maintains the angles XO,YO with the x ,y axis respectively. I told

my boss that I am having trouble with this but he said that it is

supposed to be simple and that I have all the information I need. I always

used to consider myself a good math student until today (completed my

education and always got good grades in Math). But now I am starting to

doubt my math capability! Please help me figure out how to do this. Its actually in 3 dimensions but I figured it would be

easy to do this in 2D first. How do we find the coordinates of the

point A?
