Answer:
x = 129
Step-by-step explanation:
x and 51 are same- side exterior angles and supplementary, thus
x = 180 - 51 = 129
Answer:
19degree I think
Step-by-step explanation:
the sum of each angle on the straight line is 180 degree so if you want to find x you needed to subtract 180degree-51 degree then you will get the answer
In the story “My Wonder Horse”, what key words and phrases does the author use to contrast the “legend” with the actual horse?
Answer:
what is the math?
Step-by-step explanation:
Find the measure of each missing angle
Answer:
See below;
Step-by-step explanation:
Consider the steps below;
[tex]1. Measure of Angle 1 - m< 1 + m< 2 = 180, ( Considering They Form A Linear Pair ) m< 1 + ( 145 ) = 180,\\m< 1 = 35 degrees\\\\2. Measure of Angle 2 - m< 2 = m< 4, ( Considering They Are Vertical Angles ),\\m< 2 = 145 degrees\\\\3. Measure of Angle 3 - m< 3 = m< 1, ( Vertical Angles ),\\m< 3 = 35 degrees\\\\4. By Alternate Interior Angles Theorem - m< 5 = m< 3,\\m< 5 = 35 degrees\\\\5. By Vertical Angles Theorem - m< 6 = m< 4,\\m< 6 = 145 degree\\\\[/tex]
[tex]\\\\\\6. By Corresponding Angles Theorem - m< 7 = m< 3,\\m< 7 = 35 degrees,\\\\7. By Corresponding Angles Theorem - m< 8 = m< 4,\\m< 8 = 145 degrees[/tex]
Thus, we derive such a solution;
m∠ 1 = 35°, m∠ 2 = 145°, m∠ 3 = 35° , m∠ 5 = 35° , m∠ 6 = 145° , m∠ 7 = 35° , m∠ 8 = 145°
Find the sum of the measures of the interior angles of a polygon having ten sides
Answer:
1440°
Step-by-step explanation:
Formula for sum of the measures of the interior angles of a polygon is given as:
[tex] (n-2)\times 180°\\
= (10-2)\times 180°..(plug\: n = 10)\\
= 8\times 180°\\
= 1440°

What is the volume of the cup in gallons
Examine the diagram.
A triangle has angles A, 60 degrees, 55 degrees. A line is at the top of the triangle and forms angles B, C, and 65 degrees. Angle C is opposite to angle with measure 60 degrees.
The diagram shows parallel lines cut by two transversal lines creating a triangle. Which statement can be made from the diagram?
mAngleB + mAngleC + 55° = 180°
mAngleA + 60° + 55° = 180°
mAngleC = 55°
mAngleA = 55°
Answer:
mAngleA + 60° + 55° = 180°Step-by-step explanation:
As two angles of the triangle are 60° and 55°, the measure of ∠A is:
180° - (60° + 55°) = 65°So the angles C and B measure 60° and 55°.
∠C is opposite to 60°, so is 60° as well, therefore m∠B = 55°
Statements:
mAngleB + mAngleC + 55° = 180°
Incorrect, it gives 170°mAngleA + 60° + 55° = 180°
Correct as mAngleA is 65°mAngleC = 55°
Incorrect, it is 60°mAngleA = 55°
Incorrect, it is 65°Answer: its b

If a boy 5 feet tall casts a shadow 14 feet long, what will be the length of the shadow of a tree that is 25 feet high?
Answer:
70 feet
Step-by-step explanation:
This problem can be answered by using proportions based on similar triangles.
Notice that a person and its shadow on the ground form a right angle (therefore they can be considered the two "legs" of a right angle triangle)
The same runs for the tree and its shadow.
Since the inclination of the rays of the sun are the same at the same time for both objects (the boy and the tree), their hypothenuses form the same angles with the ground and therefore belong to similar triangles.
We can create the following proportion to solve for the shadow of the tree (ST) using the information provided: the height of the boy (HB), the shadow of the boy (SB), and the height of the tree (HT)
[tex]\frac{SB}{HB} =\frac{ST}{HT}\\\frac{14}{5} =\frac{ST}{25}\\\frac{ST}{25}=\frac{14}{5} \\ST=\frac{14*25}{5}\\ST=70\,\,ft[/tex]

solve for 5/8= x-1/9
Answer:
[tex] \dfrac{53}{8} [/tex]
Step-by-step explanation:
[tex] \dfrac{5}{8} = \dfrac{x - 1}{9} [/tex]
Cross multiply.
[tex]8(x - 1) = 9 \times 5[/tex]
[tex] 8x - 8 = 45 [/tex]
[tex] 8x = 53 [/tex]
[tex] x = \dfrac{53}{8} [/tex]
Answer: x = 53/8
Step-by-step explanation:
5/8 = x-1 / 9
45 = 8(x-1)
45 = 8x - 8
-8x = -8 - 45
x = 53/8

Two trucks started toward each other at the same time from towns 500 km apart. One truck traveled at a rate of 65 km
per hour while the other traveled at 60 km per hour. After how many hours did they meet?
А
If x represents the number of hours, which of the following equations could be used to solve the problem?
Answer: 4 hrs
Step-by-step explanation: D=RT
500=(65+60)T
500=125T
T=500/125
T=4 HOURS THEY'L MEET.
Which of the following values of x is a solution to the equation 5(x-2)+7=37?
Answer:
x = 8

5x - 10 + 7 = 37
5x - 3 = 37
5x = 40
x = 8
Simplify 8x^4/x^3+7x^4 and Find the excluded values
So first what we do is we need to get the excluded values. So to get them we have: 8x^4/x^3+7x^4.
Lets factor out the second part. x^3+7x^4 = (x^(3/4)+7x))^4
So then we get 8x^4/(x^(3/4)+7x)^4
8x^4/(x^(3/4)+7x)^4
Racquetballs are sealed in a pressurized container to maintain the rebound percentage
of the balls. A racquetball has a rebound percentage of 83% when it is taken out of the
pressurized can. Suppose a racquetball is dropped from a height of 3 meters onto a
racquetball court. Use the rebound rate given to predict the height of the ball after the
first 5 bounces
Answer:
1.182 meters.
Step-by-step explanation:
We have that the initial height is 3 meters, we know that after each rebound it recovers 83% of the original height, therefore:
First bounce:
3 * 0.83 = 2.49
Second bounce:
2.49 * 0.83 = 2.0667
We can deduce a formula here:
hn = 3 * (0.83) ^ n
where is the bounce number, we know that the bounce number that we want to find the height is 5, therefore:
h5 = 3 * (0.83) ^ 5
h5 = 1.182
which means that at the fifth bounce, the height is 1.182 meters.
which two functions are inverses of each other
Answer:
f(x) = 4x, g(x) = [tex]\frac{1}{4}x[/tex]
Step-by-step explanation:
Inverse function is when you switch the x and the y and solve for x
f(x) = 4x
y = 4x
x = 4y
Now solve for x
y = [tex]\frac{1}{4}x[/tex]
g(x) = [tex]\frac{1}{4}x[/tex]
If you try that with the other functions, none of them work.
Answer:
C. f(x)= 4x, g(x)= 1/4x
Step-by-step explanation:
inverse functions are flipping x and y corrdinates so let's plug in x=1 into f(x) and get y = 4
now plug in x = 4 into g(x) and check if the answer is 1 - yes ,it is!

Segment AB falls on line 2x − 4y = 8. Segment CD falls on line 4x + 2y = 8. What is true about segments AB and CD?
They are perpendicular because they have the same slope of −2.
They are perpendicular because they have slopes that are opposite reciprocals of −2 and .
They are lines that lie exactly on top of one another because they have the same slope and the same y-intercept.
They are lines that lie exactly on top of one another because they have the same slope and a different y-intercept.
Answer:
They are perpendicular because they have slopes that are opposite reciprocals of −2 and .Step-by-step explanation:
The given lines are
[tex]2x-4y=8[/tex]
[tex]4x+2y=8[/tex]
Let's rewrite each equation in the form [tex]y=mx+b[/tex]
[tex]2x-4y=8\\2x-8=+4y\\y=\frac{2x-8}{4} \\y=\frac{x}{2}-2[/tex]
[tex]4x+2y=8\\2y=8-4x\\y=\frac{8-4x}{2}\\ y=4-2x[/tex]
Now, let's use the perpendicular rule
[tex]m_{1} \times m_{2} =-1\\\frac{1}{2} \times (-2)=-1 \implies -1=-1[/tex]
As you can observe, the slopes satisfy the perpendicular rule, that means the lines are perpendicular.
Therefore, the right answer is the second choice because it states the rule of perpendicularity between the given lines.
Answer:
They are perpendicular because they have slopes that are opposite reciprocals of −2 and .

Solve the equation, 2x + 1 = 3, for x. Which of the following properties of equality did you apply? Question 11 options: A) Addition and division B) Addition and multiplication C) Subtraction and multiplication D) Subtraction and division
Answer:
D
Step-by-step explanation:
2x+1=3
-1 on both sides: 2x=2, then divide by two. You get x=1
For this you would use D, subtraction and division
Answer:
x = 1
D) Subtraction and Division
Step-by-step explanation:
2x + 1 = 3
(2x + 1) - 1) = (3) - 1 ←
2x = 2
(2x)/2 = (2)/2 ←
x = 1
In the places where I put the arrows is where I applied the properties. I used subtraction and division to solve.
