    Thank you zuri125 for your help so far.

    Yes, I'm also trying to find the angle or bearing from the first point X to the following points - A, B & C.

    I was thinking that if Excel could calculate the answer in degrees clockwise then I could later convert these into compass directions.

    For example, I would be able to calculate that Point A is 180 metres in a southeasterly direction (or 135 degrees clockwise) from Point X.

    Thanks again.

    The standard angle measured from the x-axis (East) is:
    =ATAN(North/east)*(180/pi())
    For point (1) at 250E by 100 N, then
    angle = ATAN(-100/150)*180/PI() = -33.69 deg. below the horizontal. However, you used the word bearing, which I assume means an angle measured from the north-axis, so 90 - (-34) = 124 deg.
