Answer:
A. 80
Step-by-step explanation:
No math necessary. You know the brace needs to be longer than the distance between posts, so cannot be 4, 15, or 42 inches. The only answer choice longer than 64 inches is the correct one:
80 inches
Answer = 4 ft
Radius = Circumference / (pi x 2)
Radius = 8 / (4 x 2)
Radius = 4
diagonal = sqrt(a^2 +b^2)
20 = sqrt(12^2 +b^2)
20= sqrt(144+b^2)
20^2 = 144 + b^2
400 = 144 + b^2
256 = b^2
b = sqrt(256) = 16
it is 16 inches wide
