b) In the diagram below, two lines are drawn. Explain how you could determine the values
of b, c, and d, using at least two of the following terms: linear pair, vertical angles,
congruent, & supplementary. ( 3 points)
b
U
40°
d
Answer/Step-by-step explanation:
When twi straight lines intersect, they form 2 pairs of opposite vertical angles that are congruent.
In the diagram given, the following pairs of vertical angles are formed:
<c and 40°
<b and <d
<c = 40° (vertical angles are congruent)
<b and 40° are linear pairs. They are both supplementary. Therefore:
<b = 180° - 40
<b = 140°
<d = <b (vertical angles)
<d = 140° (substitution)

Step-by-step explanation:
Given:
[tex]DG = 10[/tex]
See attachment for complete question.
From the attachment, we can conclude that:
[tex]x + 1 + 2x - 15 = DG[/tex]
Substitute 10 for DG
[tex]x + 1 + 2x - 15 = 10[/tex]

The given trig function consist of trig values of common angles;
The values that represent the solution to [tex]\mathbf{cos \left(\dfrac{\pi}{4} - x\right)} = \dfrac{\sqrt{2} }{2} \cdot sin \, x[/tex], x ∈ [0, 2·π) are;
[tex]x = \left\{\dfrac{\pi}{2} , \, or \ \dfrac{3 \cdot \pi}{2} \right \}[/tex]
Reason:
The given function is presented as follows;
[tex]cos \left(\dfrac{\pi}{4} - x\right) = \dfrac{\sqrt{2} }{2} \cdot sin \, x[/tex]
Where;
x ∈ [0, 2·π)
We have;
cos(A - B) = cos(A)·cos(B) - sin(A)·sin(B)
[tex]cos \left(\dfrac{\pi}{4} \right) = \dfrac{\sqrt{2} }{2}, \ sin\left(\dfrac{\pi}{4} \right) = \dfrac{\sqrt{2} }{2}[/tex]
Which gives
[tex]cos \left(\dfrac{\pi}{4} - x\right) =\dfrac{\sqrt{2} }{2} \cdot cos \, x + \dfrac{\sqrt{2} }{2} \cdot sin \, x[/tex]
Therefore, we get;
[tex]\dfrac{\sqrt{2} }{2} \cdot cos \, x = \dfrac{\sqrt{2} }{2} \cdot sin \, x - \dfrac{\sqrt{2} }{2} \cdot sin \, x = 0[/tex]
cos x = 0
[tex]cos \left(\dfrac{\pi}{2} \right) = 0[/tex]Therefore;
The possible solutions (x-values) to cos x = 0 are; [tex]0 \leq \dfrac{n \cdot \pi}{2} \leq 2 \cdot \pi[/tex]Where;
n = 1, 3, 5, ...
x ∈ [0, 2·π)
We get;
[tex]x = \left\{\dfrac{\pi}{2} , \, or \ \dfrac{3 \cdot \pi}{2} \right \}[/tex]Learn more here:

15.472 million kilometers
77.792 million kilometers
154.72 million kilometers
777.92 million kilometers
Answer:
the answer is 777.92 million kilometers
Step-by-step explanation:
The distance between Jupiter and Sun is 777.92 million km
What is distance?Distance is defined to be the magnitude or size of displacement between two positions.
Given that the distance between Earth and Sun is 149.6 million km and Jupiter is about 5.2 times farther away from the Sun than Earth is,
Therefore, distance between Sun and Jupiter is = 149.6 × 5.2 = 777.92 million km
Hence, the distance between Jupiter and Sun is 777.92 million km

Area is Length x width.
Area = 4x * 5
Area = 20x
Replace A in the inequality:
Now you have 100 <= 20x <= 1,000
Now solve for x by dividing all 3 by 20:
5 <= x <=50
Check to see if they are viable:
4(5) x 5 = 20 x 5 = 100
4(50) x 5 = 200 x 5 = 1,000
Since the lowest number equals 100 and the largest number equals 1,000 all values of x would be viable. The answer is YES.
0.00105 in scientific notation
Answer:
1.05 × 10^-3
Step-by-step explanation:
The decimal number 0.00105 in scientific notation is [tex]1.05 \times 10^{-3}.[/tex]
Scientific notation is a way to represent numbers that are either very large or very small.
It consists of two parts: the coefficient and the exponent.
The coefficient is a decimal number between 1 and 10, and the exponent indicates the power of 10 by which the coefficient is multiplied.
In the case of 0.00105, we can express it in scientific notation as [tex]1.05 \times 10^{-3}.[/tex]

Line m is represented by the equation 2x + 4y - 12. Which of the following equations represents a line perpendicular to line m and intercects line m at its y-intercept?
-2x + y = 3
- 2x + y = 12
4x - 2y = 3
4x - 2y = 12
Answer:
A) -2x + y = 3
Step-by-step explanation:
The equation of the line that is perpendicular to the given line and passes through its y-intercept is -2x + y = 3.
We are given that;
The equation= 2x + 4y - 12
Now,
The given line is 2x + 4y - 12 = 0.
To find the slope of a line perpendicular to this line, we need to find the slope of the given line first.
Rewrite the equation in slope-intercept form which is given by:
y = mx + b
where m is the slope and b is the y-intercept.
2x + 4y - 12 = 0
4y = -2x + 12
y = (-1/2)x + 3
Hence, the slope of the given line is -1/2.
The slope of a line perpendicular to this line is the negative reciprocal of this slope which is given by:
[tex]m(perpendicular)[/tex] = -1/m = -1/(-1/2) = 2
To find an equation of a line that passes through the y-intercept of the given line and has a slope of 2.
The y-intercept of the given line can be found by setting x = 0:
2(0) + 4y - 12 = 0
y = 3
Hence, the y-intercept of the given line is 3.
The equation of a line with a slope of 2 and passing through (0,3) can be found using point-slope form which is given by:
y - y1 = m(x - x1)
where (x1,y1) = (0,3) and m = 2.
Substituting these values we get:
y - 3 = 2(x - 0)
y - 3 = 2x
y = 2x + 3
Therefore, by the equation answer will be -2x + y = 3.

17. The distance traveled at a constant speed varies
directly with the amount of time traveled. Sara
drove 200 miles at a constant speed of 50 mi/hr.
Holly drove for the same amount of time as Sara
but at a constant speed of 65 mi/hr. Find the
distance traveled by Holly. Justify your answer.
Hurry plz
Answer:
260 miles
Step-by-step explanation:
Sara made it to her destination in four hours, while Holly made it to her destination traveling 260 miles. This can be calculated by taking Sara's 200 miles, and dividing it by 50 mph to get a total of four hours spent driving. If Holly is also driving for four hours, but instead traveling at 65 mph, you can take 65 and multiply it by four hours to get a total of 260 miles. Hope this helps!

In this figure, a line through points x and y will ______.
A. Be perpendicular to AB but not bisect it
B. Be the perpendicular bisector of AB
C. Bisect AB but not perpendicular
D. Be unrelated to AB
Answer:
B
Step-by-step explanation:
From the figure, its clear that the compass drew arcs like below:
With A as centre, and more than half of the length of AB as radius, one arc is drawn.
With the same radius, with B as centre, another arc is drawn.
The points of intersections of the arcs are X and Y.
Clearly, this is the construction of a perpendicular bisector of the line segment AB.
Hence, if we draw a line segment through XY, it will be a perpendicular bisector of AB.
