Answer: 35 ft

Explanation:

Given

Vertical height from the eyes of the person to the top of the flag is
X-5

Horizontal distance is
$30\ ft$

The angle of elevation is
$45^(\circ)$

From the figure, we can write

$\Rightarrow \tan 45^(\circ)=(X-5)/(30)\\\Rightarrow 1=(X-5)/(30)\\\\\Rightarrow X-5=30\\\\\Rightarrow X=35\ ft$
