Using the method of least squares, compute the most probable coordinates of station U in the figure to thebelow by the least squares intersection procedure. The following equally-weighted horizontal angles were observed from control stations R, S, and T
θ1 = 50°06'50" θ2 = 101°30'47"
θ3 = 98°41'17" θ4 = 59°17'01"
The coordinates for the control stations R, S, and T are
xr = 865.40 xs = 2432.55 xt = 2865.22
yr = 4527.15 ys = 2047.25 yt = 27.15
