As it is a square all sides are equal so all sides are 12 feet long.
how many posts on one side?
First we find out how many lengths of 3 we have for 1 side:
12 / 3 = 4
And then multiply this by the amount of sides
4 * 4 = 16
We need 16 posts

Answer:
From figure A
The value of ∠ B = 75.74° , ∠ C = 70.26° and AB = 27.37
From figure B
The value of ∠ A = 42.8° , ∠ B = 106.2° and AC = 30.04
Step-by-step explanation:
<u>Given first figure as :</u>
AC = 28.2
BC = 16.5
∠ A = 34°
Let AB = c
<u>From law of sines</u>
= =
Or, =
or, =
Or, 29.506 =
Or, Sin B =
Or, Sin B = 0.955
∴ ∠B = 0.955
I.e∠ B = 75.74
Now, ∠ C = 180° - ( ∠A + ∠B )
Or, ∠ C = 180° - ( 34° + 75.74° )
Or, ∠ C = 70.26°
Now, Again
=
so, =
Or, =
Or, c = 29.09 × 0.9412
∴ c = 27.37
I.e AB = 27.37
Hence, The value of ∠ B = 75.74° , ∠ C = 70.26° and AB = 27.37
<u>From figure second</u>
Given as :
AB = c= 12
BC = a = 16
∠ C = 31°
let AC = b
<u>From law of sines</u>
= =
Or, =
or, =
or, =
Or, = 23.52
∴ Sin A =
I.e Sin A = 0.68
Or, ∠ A = 0.68
or, ∠ A = 42.8°
Now, ∠ B = 180° - ( 31° + 42.8° )
Or, ∠ B = 106.2°
Now, =
or, =
Or, =
or, b = 31.3×0.96
∴ b = 30.04
Hence The value of ∠ A = 42.8° , ∠ B = 106.2° and AC = 30.04

Answer:
300ft
Step-by-step explanation:
Answer:
A. ¹/27
Step-by-step explanation:
✔️Volume of large sphere = ⁴/3πr³
r = 18.6 in.
Volume of large square = ⁴/3*π*18.6³ = 26954.26 in.³
✔️Volume of small sphere = ⁴/3πr³
r = 6.2 in.
Volume of small sphere = ⁴/3*π*6.2³ = 998.31 in.³
✔️Ratio of the volume of the smaller sphere to the larger sphere = 998.31 : 26954.26
= 1 : 27
Therefore, the volume of the large sphere is ¹/27 of the volume of the small sphere.
