Thanks for asking the question!

ANSWER::

In triangle ABC,

tan Ф = x/2 ................. equation 1

In triangle DCE,

tan Ф = (2-x)/4 ................... equation 2

Equating both equation 1 and 2

x/2 = (2-x)/4
2x = 2-x
3x = 2
x = 2/3 ft.

(a) In triangle ABC (by Pythagoras theorem)

      AC = √(AB² + BC²) = (2√10)/3 ft.

(b) In triangle CDE ,

     DE = 1 - (2/3) = 4/3 ft.
     CD = 4ft.
So, by Pythagoras Theorem 
     CE = √(CD² + DE²) = (4√10)/3 ft.

(c) In triangle AGE , (by Pythagoras Theorem)
      AE = √(AG² + GE²) = 2√2 ft.

Hope it helps!
