Okay so far we have three usable coordinates:
2 4.73 House corner
275 2.92 House corner
314 5.29 House corner
All 3 are in the format <length> <angle> and need really to be in the format <length> <length> as construction lines for my house outline.
This is certainly one of those sine calculations (opposite/hypotenuse) to gain the opposite end of the construction line needed to draw the house outline.
I downloaded Trimble Sketchup to see if we can draw a house outline using this method.
