In the diagram, B, E and D are pints in the same horizontal plane. AB and CD are vertical poles. Steel cables AE and CE anchor the poles at E. Another steel cable connects A and C. CE = 8.6 m, BE = 10 m, ∠AEB = 40°, ∠AEC = 70° and ∠CED = 27° Diagram Calculate the:
  1. 7.1
    Height of pole CD
    (2)
    1. 7.2
      Length of cable AE
      (2)
      1. 7.3
        Length of cable AC
        (4)
        (8)
