m∠DEA = m∠BEC = 4x
m∠DEA = m∠BEC = 4(14)
m∠DEA = m∠BEC = 56°
m∠AEB = m∠CED = [360 - 2(56)] ÷ 2
m∠AEB = m∠CED = [360 - 112] ÷ 2
m∠AEB = m∠CED = 248 ÷ 2
m∠AEB = m∠CED = 124°

Answer:
C - The relationship represents a function because each input gives one unique output.
Step-by-step explanation:
To see if it is a function we can do the line test where we have a vertical line and "drag" it along the line. As long as it only hits the line once in every situation it is a function! We can see this passes and therefore the answer is c.
(why is it not d? you can have a non-linear line, but still have a function)
Find the missing side of each triangle. Round your answers to the nearest tenth if necessary. (Please Show your work)
Answer:
11.2 mi
Step-by-step explanation:
1. We can use the Pythagorean Theorem (a^2 + b^2 = c^2) to find the missing leg, b, of the triangle.
[tex]9^2 + b^2 = 14.4^2[/tex]2. (Solving)
Step 1: Simplify both sides of the equation.
[tex](9*9)+b^2 = 14.4 * 14.14[/tex] [tex]81 + b^2 = 207.36[/tex] [tex]b^2 + 81 = 207.36[/tex]Step 2: Subtract 81 from both sides.
[tex]b^2 + 81 - 81 = 207.36-81[/tex] [tex]b^2 = 126.36[/tex]Step 3: Take the square root of both sides and round to the nearest tenth.
[tex]\sqrt{b^2} = \sqrt{126.36}[/tex] [tex]b = \sqrt{126.36}[/tex] b ≈ 11.2Therefore, x = 11.2 mi.

assume lines p and q intersect to form adjacent angles 1 and 2.
if m<1 = (4x-3) and m<2 = (3x+8). find the value of x such that <1 is supplementary to <2
Answer:
x=25
Step-by-step explanation:
they are supplementary and adjacent, thus you do 4x-3+3x+8=180, simplify and get 7x+5=180, subtract 5 from 180 which is 175, then ending up with 7x=175 and 175/7 is 25.

let the interior angles of the given triangle be angle a b c respectively.
116+a=180 (Sum of angles on a straight line.)
a=180-116
a=64
.......
112+b=180(Sum of angles on a straight line.)
Sum of angles on a straight line.)b=180-112
b=68
....
angle a +b+c=180 (Sum of angles of a triangle)
64+68+c=180
c=180-132
c=48
.,....
angle c +X =180(Sum of angles on a straight line.)
48+X=180
X=132
Therefore the value of X is 132.
2.
solution,
Let the remaining interior angle of the given triangle be y.
Then,
y+108=180(Sum of angles on a straight line.)
y=72
Again,
2x+X+y=180(Sum of angles of a triangle)
3x+72=180
3x=108
X=108÷3
X=36
Therefore the value of X is 36.
3.
solution,
let the remaining interior angle of the given polygon be a and b .
Then,
100+b=180(Sum of angles on a straight line.)
b=80
......
Again,
a+b+110+90=360(Sum of interior angle of the polygon)
a+80+200=360
a+280=360
a=80
.....
a+X=180(Sum of angles on a straight line.)
80+X=180
X=100
Therefore the value of X is 100.
4.
solution,
The given triangle is an isosceles triangle.So their base angles are equal .
43+43+X=180(Sum of angles of a triangle)
X=180-86
X=94
Therefore the value of X is 94.
5.
solution,
Opposite angles of a parallelogram is equal
So ,
X=125
Therefore the value of X is 125.
6.
solution,
Let the remaining interior angle of the triangle be a .
Then,
a+117=180 (Sum of angles on a straight line.)
a=63
Now,
a+X+83=180(Sum of angles of a triangle)
63+83+X=180
146+X=180
X=34
Therefore ,the value of X is 34.

Answer:
[tex]x=1[/tex]
Step-by-step explanation:
[tex]6\left(x-3\right)+10=2\left(4x-5\right)[/tex]
We'll use the distributive property to multiply 6 by (x-3):
[tex]6x-8 +10=2(4x-5)[/tex]
*Distributive property*, multiply 2 by (4x-4)
[tex]6x-8=8x-10[/tex]
Add 8 from both sides:
[tex]6x-8+8=8x-10+8[/tex]
[tex]6x=8x-2[/tex]
Subtract 8x from both sides:
[tex]6x-8x=8x-2-8x[/tex]
[tex]-2x=-2[/tex]
Divide both sides by -2:
[tex]\cfrac{-2x}{-2}=\cfrac{-2}{-2}[/tex]
[tex]x=1[/tex]

If a car travels 32.5 miles in 1.5 hours, than how long will it take to travel 26 miles at this speed?
Answer:
Is this for math?
Step-by-step explanation:
The exterior angles of a pentagon are 115° , 2x° , 3x°, x° and x° . Calculate the value of x.
Sum of the exterior angles of a pentagon = 360
⇒ 115 + 2x + 3x + x + x = 360
[simplify the x terms and subtract 115 from both sides]
7x = 360 - 115 [divide both sides by 7]
x = 35Find the equation of the quadratic function given the vertex and a point on the parabola.
v= (3,0), p=(1,4)
Answer:
y = x² - 6x + 9
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k ) = (3, 0 ) , then
y = a(x - 3)² + 0
To find a substitute (1, 4) into the equation
4 = a(1 - 3)² = a(- 2)² = 4a ( divide both sides by 4 )
1 = a
y = (x - 3)² = x² - 6x + 9
Titus took 30 minutes to walk 2 miles at a constant
rate. Let d represent the distance Titus walks, in miles, after t minutes. Here are your constants of proportionality from the previous screen: 15 and 15. Write two different equations to represent the
relationship between d and t.
If Titus walked 7.5 miles at this same rate, how many
minutes would it take?
HEEEEEELLLLLPPPPP
Constant of proportionaility #1 2/30 = 1/15
Constant of proportionaility #2 d/t

Relationship: equality
Reason: they all represent velocity and they tell us that velocity is constant.
-------------------------------------------------------
15 and 1/15 (answer)
Steps:
Given
Time (t) = 30 minutes
distance (d) = 2 miles
To determine the first constant of proportionality
Let time be directly proportional to distance.
t = kd
Where k is the constant of proportionality
Make k the subject
k = t/d
Substitute values for t and d
k = 30/2
k = 15
To determine the second,
Let distance be directly proportional to time.
d = kt
Make k the subject
k = d/t
Substitute values for d and t
k = 2/30
k = 1/15
Hence, the constant of proportionality are
15 and 1/15

Answer:
2/5 or .4 as a decimal
Step-by-step explanation:
we can't do anything in the Parentheses so we distribute the -2.5 giving us the equation
-10x+10=6
we subtract both sides by 10
so now our equation is
-10x=-4
we divide both sides by -10
this leaves us with -4/-10 which is simplified to 2/5 or .4 as a decimal

Can someone please help me?
Answer:
x ≈ 30.1°
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos x = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{HJ}{GJ}[/tex] = [tex]\frac{45}{52}[/tex] , then
x = [tex]cos^{-1}[/tex] ( [tex]\frac{45}{52}[/tex] ) ≈ 30.1° ( to the nearest tenth )
Answer:
We are going to use Cosine [tex]\frac{adjacent}{Hypotenuse}[/tex]
[tex]\frac{45}{52}[/tex]
Now, we use the inverse of cosine
[tex]cos^{-1} (45/52) = 30.1[/tex] (rounded to the nearest tenth of a degree)
your answer is x = 30.1 degrees.

My teacher asked for me to specify which two theorems I used. And I don't know. Here is my work can someone help please.
Isosceles Right Triangle Reflection to prove ASA Congruence
1. Answer the following questions:
A. What line of reflection did you choose for your transformation?
- I used the y-axis as my line of reflection.
B. How are you sure that each point was reflected across this line?
- I am sure because the sides are all opposite, but the numbers stayed the same.
C. What reflection rule did you apply to your triangle?
- (x, y) ➟ (-x, y)
2. What other properties exist in your triangle? Discuss at least two theorems you learned about in this module that apply to your triangle. Make sure to show evidence by discussing your triangle's measurements.
- I learned that if two sides of my triangle are congruent then the angles opposite of them are congruent as well. The third angle is 90 degrees.
3. Did your triangle undergo rigid motion? Explain why.
- Yes, it did. It did because the distance and position stayed the same while the points and the plane moved.
Answer:
Actually you did everything right
Step-by-step explanation:
yes
This question requires proving congruency of triangles in a given co-ordinate system we by use of ASA(angle side angle) theorem.
Types of triangles and it's properties.An isosceles right angle triangle has two equal sides and the corresponding angles will also be equal it will be of 45° - 45° - 90°.
The hypotenuse will be [tex]\sqrt{2}[/tex] times of the equal sides.
A. We have chosen x-axis as a line of refection.Reflection along x-axis idicates rotation of 180° along x axis.
B. We are sure that each point is reflected accross this line because base has same magnitude but the signs have changed and rotation along x-axis doesn't change the value of y co-ordinate.
C. Rotaion along X-axis by 180°.
