What is Law of Cosines?A planar triangle's side's square is equal to the sum of the squares of the other sides minus the product of those sides and the cosine of the angle between them, divided by two.
We can use the Law of Cosines to find the length of side k:
k² = l² + m² - 2lm cos(K)
where K is the angle opposite side k.
In this case, we have l = 2.4 inches, m = 4.2 inches, and K = 159°. Substituting these values into the formula, we get:
k² = (2.4)² + (4.2)² - 2(2.4)(4.2)cos(159°)
Using a calculator to evaluate the cosine, we get:
k² = 5.76 + 17.64 - 19.96(-0.987688)
k² ≈ 43.11
Taking the square root of both sides (and rounding to the nearest tenth), we get:
k ≈ 6.56 inches
Therefore, the length of side k is approximately 6.56 inches.

B. y = 2.5x + 20
C. y = 8x
D. y = 0.125x
Answers
Answer: d, a, and c
Step-by-step explanation:
Part(A)
The ordered pair (2.5, 20) represents $2.50 for 20 hours. the correct option is A.
Part(B),
Yes. the line passes through the origin. The correct option is A.
Part(C),
The linear equation represented by the graph is y = 8x. The correct option is C.
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line:-
y = mx + c
m = slope
c = y-intercept
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given that coordinates are (0.5, 4), (1, 8), (1.5, 12), (2, 16), and (2.5, 20).
Part(A),
The ordered pair (2.5,20) represents that the earning is $20 for the work of 2.5 hours.
Part(B),
The slope of the line will be calculated as,
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Slope = ( 8 - 4 ) / ( 1 - 0.5 )
Slope = 4 / 0.5
Slope = 40 / 5
Slope = 8 hours
The y-intercept is calculated as,
y = mx + c
16 = ( 2 x 8 ) + c
c = 16 - 16
c = 0
Hence, the line passes through the origin.
Part(C),
The equation of the line will be written as,
y = mx + c
y = 8x + 0
y = 8x

Answers
Answer and Step-by-step explanation:
Hello!
You are told to round the number to the nearest whole number.
That means if the decimal is lower than 5 in the tenths place, the number would round down, and if the decimal is equal to or higher than 5 in the tenths place, the number would round up.
[tex]5\frac{5}{6}[/tex] is equal to 5.833. The number 8 is greater than 5, so the number rounds up to 6.
[tex]6\frac{1}{9}[/tex] is equal to 6.111. The number 1 is less than 5, so the number rounds down to 6.
Now we have the equation n - 6 = 6.
We solve for n.
Add 6 to both sides.
n = 12
n is equal to 12.

Answers
Answer:
2/3
Step-by-step explanation:
Answer:
a=2/3
Step-by-step explanation:
1. y=a(x-x1)(x-x2) is a formula for a parabola, x1 and x2 being points where y=0 so in the equation y=a(x-3)(x+2), you know
x1=3, x2=-2
2. Find distance between 3 and -2, which is 5
3. bh/2=A --> 5h/2=10 --> h=4 (h is height)
4. when x=0, y=-6a, y=a(0-3)(0+2)
5. because parabola opens upward, the point of the vertex must be (_, -4)
6. -6a= -4
a=2/3

Two pairs of socks and a pair of slippers cost $30. Five pairs of socks and a pair of slippers cost $42. Let u
represent the cost of a pair of socks and let y represent the cost of a pair of slippers.
Identify the system of equations that represents the situation and identify the solution to the system of equation.
Answers
Answer: See explanation
Step-by-step explanation:
The information given in the question can be turned into an equation as:
2u + y = 30 ........ i
5u + y = 42 ........ ii
Subtract i from ii
3u = 12
u = 12/3 = 4
A pair of socks cost $4
Since 2u + y = 30
2(4) + y = 30
8 + y = 30
y = 30 - 8 = 22
A pair of slippers cost $22

Add all the angles in triangle 2
84 + 36 = 120
The angle that is divided between triangle 1 and 2 measures 90 degrees so we are gonna add it to the total of triangle 2
120 + 90 = 210
Because no angles in a triangle measures 210 we are gonna subtract 180 from .
210 - 180 = 30
The missing angle in the second triangle is;
180 - 120 = 60 degrees
The total we got after subtracting 180 from 210 is the missing angle for the divided side of triangle 1.
Now that we have 2 angles we can now find “?”
To find “?” we are gonna add the two angles we have and subtract it from 180.
86 + 30 = 116
180 - 116 = 64
Therefore “?” is equal to 64 degrees.
