We know that the diameter of the inner circle (d) and the side of a regular octagon (s) are tied by the formula:
d = (1 +√2) × s
The inverse formula is:
s = d / <span>(1 +√2)
Plugging in numbers:
s = 7 (1 + </span>√2)
= 2.9 ft
Therefore the correct answer is A) <span>2.9 feet</span>

Answer:
x=7
Step-by-step explanation:
8(1X/4 +12 - 1 x 1/2X)=82
8(X/4 +12-1 x 1/2 x X)=82
8(X/4+ 12 - 1/2x)=82
8 X x/4 + 96+8 X -x/2=82
2x +96 +8 X -x/2=82
2x +96+ 8(-1)/2=82
2x +96 -8x/2 =82
2x+96-4x=82
-2x+96=82
-2x=-14
x=7
