Answer:
When we know all 3 sides we use the law of cosines
a = 47
b = 11
c = 38
cos (A) = (b^2+c^2-a^2) / (2bc)
cos (A) = -0.7703349282
Angle A = 140.38
cos (B) = (a^2 + c^2 -b^2) / (2ac)
cos (B) = 0.9888017917
Angle B = 8.5826 degrees
cos (C) = (a^2 + b^2 -c^2) / 2ab
cos (C) = 0.8568665377
cos (C) = 31.033 degrees
Angle W would be the smallest angle so it equals
31.033 degrees or rounded to nearest tenth
31.03

Answer:
X=SMALL BOX.
Y=LARGE BOX
THEREFORE,X+Y=21
X=21-Y
THEREFORE,25(21-Y)+70Y=1110 POUNDS
525-25Y+70Y=1110
525+45Y=1110
45Y=1110-525
45Y=585
Y=585/45
Y=13 .
Therefore,13 large box and8 small box..
The range of the function f(x) = |x| is [0,∞)
<h3>How to determine the range?</h3>
The function is given as:
f(x) = |x|
The above is the parent equation of an absolute value function.
The above function cannot output any negative value.
This means that:
ƒ(x) >= 0
As an interval notation, we have:
[0,∞)
Hence, the range of the function f(x) = |x| is [0,∞)

Answer:
Step-by-step explanation:
area of sector = {Ф ( in degrees)/360}πr²
Ф = 60
π=3.14
r=10
area = (60/360) x 3.14 x 10²
= (1/6)x3.14 x100 = (1/6)x314= 314/6 = 52.33
