Answer:
 22.3 ft
Step-by-step explanation:
The height of the portion of the pole that is above Ella's eyes can be found using the tangent function.
 Tan = Opposite/Adjacent
 tan(25°) = (height above eyes)/(36 ft)
 height above eyes = (36 ft)·tan(25°) ≈ 16.8 ft
Then the height of the flagpole is ...
 5.5 ft + 16.8 ft = 22.3 ft
The flagpole is 22.3 feet high.
