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
Answer:
see below
Step-by-step explanation:
The costs are
2230.80 + .03 b where b is the board foot
the income was 1.13b
Profit is income - costs
Profit = 1.13b - (2230.80 + .03 b)
Distribute
= 1.13b - .03b - 2230.08
= 1.10b - 2230.08
Profit is when the money is greater than 0
(breaking even is 0)
0 <1.10b - 2230.08
Add 2230.08 to each side
2230.08 < 1.10b - 2230.08 + 2230.08
2230.08 < 1.10b
Divide by 1.10
2230.08/1.10 < 1.10b/1.10
2027.345455 <b
They must sell at least 2027.345 board feet of lumber per day to make a profit
