Tan88.05= MH/VH donc VH = MH/tg88.05 = 1/tan88,05 . MH = 0,03405MH
tan 86,82 = MH/HR donc HR = MH/tan86,82 = 1/tan86,05 . MH = 0,05556MH

0,03405MH + 0,05556MH =  0,08961MH = VH + HR = VR = 182.37 m

donc MH = 182.37/0.08961 = 2035 m

sin 88.05 = MH/VM  = 2035/VM  et donc VM = 2035/sin88.05 = 2036 m
