    I know the x and y coordinates of PointA, I know the distance between PointA and PointB, and I know the relative angle to PointB from PointA. How do I find the x and y coordinates of PointB?

    Create a triange with the hypotenuse as the distance between the points. Then simply use the trig formulas to work out the other lengths and hence deduce the x and y coordinates.

    \huge  cos\theta = \frac{a}{h}
