WILL GIVE BRAINLIEST!! ABC is a triangle. Find the size of the largest angle in the triangle. Give your answer in degrees correct to 3 significant figures.
Answer:
98.2°Step-by-step explanation:
The largest angle is opposite to the largest side.
Since the largest side is BC, the largest angle is A.
Work out the angle measure using the law of cosines:
cos ∠A = (b² + c² - a²)/(2bc)cos ∠A = (3² + 7² - 8²)/(2*3*7)cos ∠A = -0.14286m∠A = arccos (-0.14286)m∠A = 98.2°Can someone help me with this

Answer:
x= 8
Step-by-step explanation:
Half of a circle or a straight line is equal an angle of 180 degrees. Therefore, both the measurements of angles RPS and QPR are equal to 180 degrees.
3x + 12 + 7x + 88 = 180
Add like terms
10x + 100 = 180
-100. -100
10x = 80
/10. /10
x = 8
Two dice, a red and a blue, are rolled. Find the probability that both dice show sixes
Answer:
2.78%
Step-by-step explanation:
So to get a 6 when rolling a six-sided die, probability = 1 ÷ 6 = 0.167, or 16.7 percent chance. So to get two 6s when rolling two dice, probability = 1/6 × 1/6 = 1/36 = 1 ÷ 36 = 0.0278, or 2.78 percent.

The center of an ellipse is (-4,0) one vertex is (-8,0) and one co-vertex is (-4,1). Write the equation of the ellipse
Answer:
The equation of the ellipse is;
[tex]\dfrac{(x + 4)^2}{4^2} + \dfrac{(y - 0)^2}{1^2} = 1[/tex]
Step-by-step explanation:
The parameters of the ellipse are;
The location of the center of the ellipse = (-4 0)
The coordinates of the vertex of the ellipse = (-8, 0)
The coordinates of the the co-vertex = (-4, 1)
The general form of the equation of an ellipse is presented as follows;
[tex]\dfrac{(x - h)^2}{a^2} + \dfrac{(y - k)^2}{b^2} = 1[/tex]
The center of the above equation of an ellipse = (h, k)
The vertex of the above equation are; (h - a, k) and (h + a, k)
The co vertex of the above equation are; (h, k - b) and (h, k + b)
By comparison, we have;
h = -4, k = 0
For the vertex, we have;
When
h - a = -8
∴ -4 - a = -8
-a = -8 + 4 = -4
a = 4
When
h + a = -8
-4 + a = -8
∴ a = -4
a = 4 or -4
We note that a² = 4² = (-4)²
For the covertex, we have;
When
k - b = 1
0 - b = 1
b = -1
When k + b = 1
0 + b = 1
b = 1
∴ b = 1 or -1
b² = 1² = (-1)²
We can therefore write the equation of the ellipse as follows;
[tex]\dfrac{(x - (-4))^2}{4^2} + \dfrac{(y - 0)^2}{1^2} = \dfrac{(x + 4)^2}{4^2} + \dfrac{(y - 0)^2}{1^2} = 1[/tex]
Therefore;
[tex]\dfrac{(x + 4)^2}{4^2} + \dfrac{(y - 0)^2}{1^2} = 1[/tex]
Find a formula for an arithmetic sequence that begins 45, 40, 35, 30, ...
a) qn = 40+5n
b) qn = 50-51
c) 9n = 45-5(n-5)
d) 9n=45-5n
Answer:
C) 9n=45-5(n-5)....…...….......
The formula for an arithmetic sequence that begins 45, 40, 35, 30, ... will be an = 45-5(n-1). The correct option is C.
What is an arithmetic sequence?An arithmetic sequence is a series of numbers in which the difference between the next term to its previous term remains constant for the whole series. This difference is called a common difference.
Given that the arithmetic series is 45, 40, 35, 30,.. Here in the series, the first term is 45 and the common difference is d = 5.
The formula for the nth term in the arithmetic series is given below:-
an = a₁ + d ( n - 1 )
Substitute the values in the given formula above.
an = a₁ + d ( n - 1 )
an = 45 + 5 ( n - 1 )
Therefore, the formula for an arithmetic sequence that begins 45, 40, 35, 30, ... will be an = 45-5(n-1). The correct option is C.
The correct options are given below:-
a) an = 40+5n
b) an = 50-51
c) an = 45-5(n-1)
d) an=45-5n

1. A soccer field has an area (A = LW) that is represented by the polynomial 1 point
below. Which binomials could represent the possible dimensions of the
soccer field?(Hint: Use factoring)
Answer:
[tex](x + 6)(x - 6)[/tex]
Step-by-step explanation:
Given
See attachment for soccer field
Required
The possible dimension of the field
From the attachment, we have:
[tex]Area = x^2 - 36[/tex]
[tex]Length = x +a[/tex]
[tex]Width = x + b[/tex]
So, we have:
[tex]Length * Width = Area[/tex]
This gives:
[tex](x + a)(x + b) = x^2 - 36[/tex]
Express 36 as 6^2
[tex](x + a)(x + b) = x^2 - 6^2[/tex]
Express as difference of two squares
[tex](x + a)(x + b) = (x + 6)(x - 6)[/tex]
Hence, the dimension is: [tex](x + 6)(x - 6)[/tex]

using trapezoid TANK with median ōB, find the indicated base/median length.
If OB = 9.12 and AT = 5.44, find KN.
Answer:
12.8
Step-by-step explanation:
Theorem: The median of a trapezoid is parallel to each base and the length of the median equals one-half the sum of the lengths of the two bases.
OB = (1/2)(AT + KN)
9.12 = (1/2)(5.44+ KN)
Multiply both sides by 2
18.24 = 5.44 + KN
Subtract 5.44 from both sides
12.8 = KN
If OB is the median. Then the measure of the length KN of the trapezoid will be 12.8 units.
What is Geometry?It deals with the size of geometry, region, and density of the different forms both 2D and 3D.
Using a trapezoid tank with median OB.
Then the indicated base/median length will be
If OB = 9.12 and AT = 5.44.
Then the measure of the length KN of the trapezoid will be
OB = (AT + KN)/2
9.12 = (5.44 + KN)/2
18.24 = 5.44 + KN
KN = 12.8
Thus, the measure of the length KN of the trapezoid will be 12.8 units.

Create a histogram of this data.
To create a histogram, hover over each age range on the x-axis. Then click and drag up to plot the data.
Answer:
Refer to image
Step-by-step explanation:
When creating a histogram it is best to create a range for the different variables that are available.
So for the sake of covering all the possible ranges from 1 - 22, let's divide it into 5 categories.
0 - 5
6 - 10
11 - 15
16 - 20
21 - 25
Now that we have set ranges for the different variables, we then find the frequencies.
0 - 5 : 3
6 - 10 : 2
11 - 15 : 3
16 - 20 : 1
21 - 25 : 3
Now that we have all the values we can then create our histogram

Given P(A)=0.64P(A)=0.64, P(B)=0.4P(B)=0.4 and P(A\cap B)=0.356P(A∩B)=0.356, find the value of P(A\cup B)P(A∪B), rounding to the nearest thousandth, if necessary.
Answer:
Step-by-step explanation:
P(A U B) = P (A) + P (B) - P (A and B)
= 0.64 + 0.4 - 0.356
= 0.684
The value of P(A∪B) is 0.684
What is probability?Probabilities are used to determine the chances of events
The given parameters are:
P(A)=0.64,
P(B)=0.4
P(A∩B)=0.356
To find the value of P(A∪B), we make use of the following formula
P(A∪B) = P(A) + P(B) - P(A∩B)
So, we have:
P(A∪B) = 0.64 + 0.4 - 0.356
Evaluate the expression
P(A∪B) = 0.684
Hence, the value of P(A∪B) is 0.684
