Answer:

Distance between the  poles  AB and ED is 15.59 feet .

Step-by-step explanation:

By using the pythagoras theorem

Hypotenuse² = Perpendicular² + Base²

As in ΔABC

AC² = AB² + BC²

AC = 13 ft

AB = 11 ft

Put in the above

13² = 11² + BC²

169 = 121 + BC²

169 - 121 = BC²

48 = BC²

[tex]BC = \sqrt{48}[/tex]

BC = 6.93 units (Approx)

As in  ΔCDE

CE² = CD² + DE²

CE = 10 ft

DE = 5 ft

Put in the above

10² = CD² + 5²

100 = CD² + 25

100 - 25 = CD²

[tex]CD = \sqrt{75}[/tex]

CD = 8.66 ft (Approx)

Thus

Distance between the poles  AB and ED = BC + CD

                                                                    = 6.93 + 8.66

                                                                    = 15.59 feet

Therefore the distance between the  poles  AB and ED is 15.59 feet .
