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°
Calculate the:

7.1Height of pole CD(2)

7.2Length of cable AE(2)

7.3Length of cable AC(4)
