The trigonometry to do that involves a great many steps, and is beyond the
scope of a Wiki/Answers answer.
The process isn't difficult. It's just long, complicated, and boring, with a high
probability of making a mistake if it's done manually. It's almost always done
with a computer, programmable calculator, or a specialized GPS unit.

Yes, it is possible to calculate the chromaticity coordinates using absorbance values. The best way to calculate the chromaticity coordinates using absorbance values is by using the formula x = x/x+y+z.
With a protractor or use trigonometry if you know its dimensions
You calculate the coordinates using a fraction!
I am not sure what you mean; I guess some symbols disappeared when posting the question. I assume you have two given points. The idea is to calculate the slope as: slope = (difference in y-coordinates) / (difference in x-coordinates)
Use the rule of Pythagoras - calculate the distance as squareroot(deltax2 + deltay2), where deltax and deltay are the differences in the x and y coordinates, respectively.Use the rule of Pythagoras - calculate the distance as squareroot(deltax2 + deltay2), where deltax and deltay are the differences in the x and y coordinates, respectively.Use the rule of Pythagoras - calculate the distance as squareroot(deltax2 + deltay2), where deltax and deltay are the differences in the x and y coordinates, respectively.Use the rule of Pythagoras - calculate the distance as squareroot(deltax2 + deltay2), where deltax and deltay are the differences in the x and y coordinates, respectively.
