Answer:
C) 6 feet
Step-by-step explanation:
The diagram is shown in the attachment.
Using the Pythagoras Theorem,
[tex]x^2=4^2+4^2[/tex]
[tex]x^2=16+16[/tex]
[tex]x^2=32[/tex]
We take positive square root to obtain
[tex]x=\sqrt{32}[/tex]
[tex]x=4\sqrt{2}[/tex]
x=5.66ft
Rounding to the nearest feet we have x=6ft
