    ɣ1 = (2 1^ 4 )
    ɣ2 = ( 4 3^ 2)


    1-
    (2 4^ 1 ) = 35 48` 0.2302 "
    (3 4^ 2 ) = 62 35` 13.21"

    2- ( 12 & 23 )
    L12 =151.60620221 m
    L23=249.36931842 m

    3-
    α12=502124.8
    α23=123465.5
    α21=2302124.8

    4- ( 3 2^ 1 ) =
    α21 - α23 = 1063519.3

    5-
    we have to solve these eqns :
     sin(ɣ1) = k1 * sin(ɣ2

    We have to get >>> (k1 & k2 & ɣ1 & ɣ2

     k1=(L23*sin 35480.2302 )/(L12 * sin 623513.21 ) s
    So >>> k1 = 1.083875948

     (ɣ1) = k2 - (ɣ2
     k2 = 360 - ( 3 2^ 1 ) - 35480.2302 - 623513.21 s
    Take care that --- (3 2^ 1) = 1063519.3
    So  k2=155127.26s

    Now we can solve>>  sin(ɣ1) = k1 * sin(ɣ2) =1.083875948 * sin (ɣ2

    take care that
    sin (ɣ1) = [sin (k2)]*[cos(ɣ2)] [cos(k2)]*[sin (ɣ2)]1
     1.083875948 * sin(ɣ2) = [sin (k2)]*[cos(ɣ2)] [cos(k2)]*[sin (ɣ2)]1

     (ɣ2) = 671244.7s
     (ɣ1) = 874912.08s


    6-
    so we have ---
    (α14) =( α12)+ (ɣ1) =502124.8 + 874912.08
    (α14) = 138107.37


    7-
    get angel (4 2^ 1) to get length of (L14)

    (4 2^ 1) = 180 - ɣ2 - 35480.2302
    (4 2^ 1) = 562247.69

    [ sin(562247.69)]/[L14]=[sin(35480.2302)]/[L12]
     L14 = 215.8214865 m

    8-
    get coordinates of pt. 4
    E= 81.135 + 215.8214865 * sin(138107.37)
    N= 125.655 + 215.8214865 * cos(138107.37)

     pt. 4 = (225.0748602 , -35.15616465 )
