Use vectors to find the interior angles of the triangle with the given vertices. (Enter your answers as a comma-separated list. Enter your answers in terms of degrees. Round your answers to two decimal places.) (−3, −5), (2, 6), (6, 3)
Answer:
23.92°, 78.503°, and 77.577°
Step-by-step explanation:
The coordinates of the vertices of the triangle are;
X(-3, -5), Y(2, 6), Z(6, 3)
The vectors are;
z = [tex]\left \langle 2 - (-3), 6 - (-5) \right \rangle[/tex] = [tex]\left \langle 5, 11 \right \rangle[/tex]
y = [tex]\left \langle 6 - (-3), 3 - (-5) \right \rangle[/tex] = [tex]\left \langle 9, 8 \right \rangle[/tex]
x = [tex]\left \langle 2 - 6, 6 - 3 \right \rangle[/tex] = [tex]\left \langle -4, 3 \right \rangle[/tex]
[tex]cos (\alpha ) = \dfrac{z \cdot y}{\left | z \right | \times \left | y \right |}[/tex]
Therefore, we get;
[tex]cos (\alpha ) = \dfrac{5 \times 9 + 11 \times 8 }{\left | \sqrt{5^2 + 11^2} \right | \times \left | \sqrt{9^2 + 8^2} \right |} = \dfrac{133}{\sqrt{146} \times \sqrt{145} } \approx 0.91409[/tex]
α = arccos(0.91490) ≈ 23.92°
γ = The angle between -y and x
-y = [tex]\left \langle -9, -8 \right \rangle[/tex]
We get;
[tex]cos (\gamma) = \dfrac{-y \cdot x}{\left | -y \right | \times \left | x \right |}[/tex]
Therefore;
[tex]cos (\gamma) = \dfrac{-9 \times -4 + -8 \times 3 }{\left | \sqrt{(-9)^2 + (-8)^2} \right | \times \left | \sqrt{(-4)^2 + 3^2} \right |} = \dfrac{12}{\sqrt{145} \times \sqrt{25} } \approx 0.199309[/tex]
γ = arccos(0.199309) ≈ 78.503°
γ ≈ 78.503°
By angle sum property, β = 180° - (α + β)
β ≈ 180° - (23.92° + 78.503°) = 77.577°
β ≈ 77.577°
The interior angles are;
23.92°, 78.503°, and 77.577°

Step-by-step explanation:
Corresponding, alternate interior, and same side interior angles only occur in a set of parallel lines. In figure f, none of the lines are parallel. Straight angles are defined as angles that make up one side of the line, or 180 degrees, and as the picture clearly shows, this is not the case.

Construct the 95% confidence interval estimate of the mean VAS score for patients given the magnet treatment. Find the Standard error and critical value. construct the 95% confidence interval estimate of the mean VAS score for patients given the sham treatment. You may do the shortcut.
Answer:
(3.442 ; 6.558)
Step-by-step explanation:
Given :
Mean score after patient is given the magnet treatment :
Mean score, xbar = 5
Standard deviation, s = 2.4
Sample size, n = 20
The confidence interval :
Mean ± margin of error
Margin of Error = Tcritical * standard error
The critical value at 95%, df = 20 - 1 = 19
Tcritical = 2.093 (T-student distribution)
The standard error = s/√n = 2.4 / √20 = 0.5367
The margin of error = 2.903 * 0.5367 = 1.558
The confidence interval :
Xbar ± Margin of error
5 ± 1.558

The sum of three numbers is 103. The second number is 5 less than the first. The third number is 4 times the first. What are the numbers?
Answer:
The numbers are 18, 13, and 72.
Step-by-step explanation:
Let the three numbers be represented by a, b, and c.
The sum of the three is 103. Thus, we can write that:
[tex]a+b+c=103[/tex]
The second number is five less than the first. So:
[tex]b=a-5[/tex]
And the third number is four times the first. So:
[tex]c=4a[/tex]
Substitute:
[tex]a+(a-5)+(4a)=103[/tex]
Solve for a. Combine like terms:
[tex]6a-5=103[/tex]
Add five to both sides:
[tex]6a=108[/tex]
And divide both sides by six. Therefore:
[tex]a=18[/tex]
So, the first number is 18.
Since the second number is five less than the first, the second number is 13.
And since the third number is four times the first, the third number is 72.

what equations equals 28
The solutions to the equations are:
x = 21,
x = 7,
4 * 7 = 28,
3³ - 2³ = 19, and 30 - 2 = 28.
We have,
x + 7 = 28
To solve for x, we can subtract 7 from both sides of the equation:
x + 7 - 7 = 28 - 7
x = 21
So, the solution to the equation x + 7 = 28 is x = 21.
2x + 14 = 28
To solve for x, we can subtract 14 from both sides of the equation:
2x + 14 - 14 = 28 - 14
2x = 14
Next, we divide both sides of the equation by 2 to isolate x:
2x/2 = 14/2
x = 7
Therefore, the solution to the equation 2x + 14 = 28 is x = 7.
4 * 7 = 28
This equation is already solved.
The product of 4 and 7 is 28.
So, the equation 4 * 7 = 28 is true.
3³ - 2³ = 28
To solve this equation, we need to evaluate the exponentials:
3³ - 2³ = 27 - 8 = 19
Therefore, the equation 3³ - 2³ = 28 is not true; the correct value is 19.
30 - 2 = 28
This equation is already solved.
The difference between 30 and 2 is indeed 28.
So, the equation 30 - 2 = 28 is true.
Thus,
The solutions to the equations are:
x = 21,
x = 7,
4 * 7 = 28,
3³ - 2³ = 19, and 30 - 2 = 28.

-----------------------hope it helps...have a great day!!A student is trying to calculate his semester average. He knows that his test average is an 80, his quiz average is a 72, homework is a 90, and classwork is a 93. If tests and quizzes are worth 30% each, and homework and classwork are worth 20% of his overall average, what is his average? Round to the nearest tenth.
What is the mean?
As per linear equation, the average of the student is 82.2.
The mean is 83.75.
What is a linear equation?A linear equation is an equation that contains one or multiple variable with the highest power of the variable is one.
The student got test average of 80, his quiz average of 72, homework of 90, and classwork of 93.
Test is worth of 30%.
Therefore, the weightage of test is
= 80 × 30%
= 24
Quiz is worth of 30%.
Therefore, the weightage of quiz is
= 72 × 30%
= 21.6
Homework is worth of 20%.
Therefore, the weightage of homework is
= 90 × 20%
= 18
Classwork is worth of 20%.
Therefore, the weightage of classwork is
= 93 × 20%
= 18.6
Therefore, the average of the student is
= (24 + 21.6 + 18 + 18.6)
= 82.2
Now, the mean is
= (80 + 72 + 90 + 93)/4
= 83.75

X, Y and Z form the vertices of a triangle. XY = 12.4m, XZ = 10.4m and YZ = 8.7m. Find the angle ∠ YXZ rounded to 1 DP.
Answer:
43.8°
Step-by-step explanation:
Applying,
Cosine rule,
From the diagram attached,
x² = y²+z²-2yxcos∅.................... Equation 1
where ∅ = ∠YXZ
Given: x = 8.7 m, y = 10.4 m, z = 12.4 m
Substitute these values into equation 1
8.7² = 10.4²+12.4²-[2×10.4×12.4cos∅]
75.69 = (108.16+153.76)-(257.92cos∅)
75.69 = 261.92-257.92cos∅
collect like terms
257.92cos∅ = 261.92-75.69
257.92cos∅ = 186.23
Divide both sides by the coefficient of cos∅
cos∅ = 186.23/257.92
cos∅ = 0.722
Find the cos⁻¹ of both side.
∅ = cos⁻¹(0.7220)
∅ = 43.78°
∅ = 43.8°

Parallelogram T U V S is shown. Angle U is (4 x + 9) degrees and angle V is (6 x minus 29) degrees.
Which angles equal 91°?
angles T and V
angles S and U
angles U and V
angles S and T
==========================================================
Explanation:
Angles U and V are adjacent angles since they are right next to each other in the letter sequence TUVS.
When dealing with parallelograms, adjacent angles are always supplementary (meaning they add to 180).
U+V = 180
(4x+9) + (6x-29) = 180
10x-20 = 180
10x = 180+20
10x = 200
x = 200/10
x = 20
Use this x value to find each angle mentioned
angle U = 4x+9 = 4*20+9 = 89 degreesangle V = 6x-29 = 6*20-29 = 91 degreesWe can see that U+V = 89+91 = 180 which helps confirm our answer so far.
Angle V is part of the answer we want. The angle opposite this is angle T.
We can identify a pair of opposite angles by looking at letters where they are separated by some other letter between them.
Opposite angles in a parallelogram are always the same measure. Both angles T and V are 91 degrees.
That means angles U and S are each 89 degrees.
Answer:
The answer is A- angles T and V
