While basking on Seba beach of Wabamun lake (west of Edmonton), in the distance I can just barely see the very top of the three power plant chimneys over at the eastern end of the lake. Determine the height of the chimney's with error margins. Assume the earth radius r=6366km, and make appropriate measurements with error margins in the map below. (You can assume the powerplant is in Kapasiwin).
