8 times 8 is the closest you can get to 71 without going over, since 8 times 9 would be 72.

Answer: The height of street would be 3.26 feet.

Step-by-step explanation:

Since we have given that

Angle of elevation = 71°

Distance traveled = 12 feet

Angle of elevation becomes 46°.

So, the height of the street lamp post would be

$h=\dfrac{d}{\cot 46^\circ-\cot 71^\circ}\\\\h=\dfrac{12}{0.965-0.344}\\\\h=\dfrac{12}{0.620}\\\\h=3.26\ feet$

Hence, the height of street would be 3.26 feet.
