I’ve got a maths problem that I can’t figure out and I wonder if one of you delightful people on here can help me out.

Here’s the scenario:

Point A is a design location of a foundation with a given set of coordinates and a bearing and a fixed distance to a point.

Easting: 345687.837

Northing: 391242.185

Bearing: 146.034

Distance to fixed point: 2.500m

Point B is the location the foundation was installed at:

Easting: 345688.011

Northing: 391241.965

Bearing: unkown

Is it possible to calculate the new distance from the fixed point using the above data, if so how?
