If ∠ D ≡ ∠ CED then CD ≡ CE
The base angles theorem states that if the sides of a triangle are congruent, that is isosceles triangle the the angles opposite these sides, the base angles, are equal.
Here we are using the converse of base angle theorem (b)
That is if 2 angles are congruent ( base angles ) then the sides opposite these angles are congruent.
Answer:
Angle D = Angle CED, then CD=CE.b) Converse of Base Angle TheoremStep-by-step explanation:
The base angles theorem converse states if two angles in a triangle are congruent, then the sides opposite those angles are also congruent.

Answers
Answer:
a. Slope of f(x) is greater than g(x)
b. y-intercept of f(x) is less than the y-intercept of g
Step-by-step explanation:
Function f(x)
Given the function f(x)
x f(x)
-3 -0.5
-2 0
-1 0.5
0 1
Finding the slope between any two points
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(-3,\:-0.5\right),\:\left(x_2,\:y_2\right)=\left(-2,\:0\right)[/tex]
[tex]m=\frac{0-\left(-0.5\right)}{-2-\left(-3\right)}[/tex]
[tex]m=0.5[/tex]
Thus,
The slope of f(x) = 0.5
We know that the value of the y-intercept can be determined by setting x = 0, and determining the corresponding value of y.
From the given point (0, 1), we can easily observe that at x = 0, the value of y = 1.
Thus, the y-intercept of f(x) = 1
Function g(x)
Taking two points from the given graph of g(x)
(1, 0)(0, 2)Finding the slope between (1, 0) and (0, 2)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(1,\:0\right),\:\left(x_2,\:y_2\right)=\left(0,\:2\right)[/tex]
[tex]m=\frac{2-0}{0-1}[/tex]
Refine
[tex]m=-2[/tex]
Thus,
The slope of g(x) = -2
We know that the value of the y-intercept can be determined by setting x = 0, and determining the corresponding value of y.
From the given point (0, 2), we can easily observe that at x = 0, the value of y = 2.
Thus, the y-intercept of g(x) = 2
Conclusion:
FOR function f(x)
The slope of f(x) = 0.5
The y-intercept of f(x) = 1
FOR function gx)
The slope of g(x) = -2
The y-intercept of g(x) = 2
Thus:
a. Slope of f(x) is greater than g(x)
b. y-intercept of f(x) is less than the y-intercept of g

An easy way to solve problems like this is to convert the percentage into a decimal, then multiply that decimal by the whole. For example, if I had the question "What is 10% of 100?", I would first convert the 10% to a decimal. 10% is the same as 10/100, which in decimal form is 0.1. I would then multiply 0.1 by 100 to find out how much 10% of 100 is. I get 10, so my answer is 10. Hope this helps!
Jaden and Dani are both travelling by train.
Jaden's train travels 130 km in 75 minutes.
Dani's train travels 312 km.
It leaves at 15:15 and arrives at 18:30.
Work out the difference, in km/h, between the average speed of their trains.
Answers
Answer: 28.765957 km/hour
This value is approximate. Round it however you need to.
==============================================
Explanation:
Let's convert 75 minutes to hours.
75 min = (75 min)*(1 hr/60 min) = (75/60) hr = 1.25 hr
So Jaden's train takes 1.25 hours to travel 130 km. Her train's speed is
speed = distance/time
speed = (130 km)/(1.25 hrs)
speed = (130/1.25) km per hour
speed = 104 km per hour
Let A = 104, so we can use it later.
------------------------------------
Dani's train leaves at 15:15 and arrives at 18:30. We need to calculate the duration of elapsed time here.
From 15:15 to 16:00, this is a difference of 00:45, aka 45 minutes or 45/60 = 3/4 = 0.75 hours.From 16:00 to 18:00, this is a time gap of 2 hours. From 18:00 to 18:30, this is a gap of 30/60 = 0.5 hoursOverall, the length of time from 15:15 to 18:30 is 0.75+2+0.5 = 3.25 hours.
Dani's train travels 312 km in 3.25 hours.
That train's speed is...
speed = distance/time
speed = (312 km)/(3.25 hours)
speed = (312/2.35) km per hour
speed = 132.765957 km per hour, approximately
Let B = 132.765957 so we can use it later.
------------------------------------
Lastly, we subtract the values of A and B to get the final answer
C = difference in train speeds.
C = B - A
C = 132.765957 - 104
C = 28.765957 km/hour
This value is approximate. This says that Dani's train is approximately 28.765957 km/hour faster compared to Jaden's train.

Angles in a triangle
Answers
Answer
1=62
2=45
3=24
Angle 1
1 plus 118 equals 180 degrees (because both of the angles combined creates a straight angle).
1+118=180
180-118=1
1=62
Angle 2
The angles in a triangle add up to 180 degrees.
You know that angle 1 is 62 degrees.
And the other angle is 73 degrees.
You can now find angle 2.
62+73+2=180
2=180-62-73
2=45
Angle 3
Angle three is in a different triangle.
You already know that the angles in a triangle added up are 180 degrees.
The other missing angle in the triangle can be found by subtracting 73 from 180.
180-73=107
Now you know that two of the angles in the triangle are 107 and 49.
You can now find angle 3.
107+49+3=180
3=180-107-49
3=24

solve the equation 1/2x+7=18
Answers
Answer: 22
Step-by-step explanation:
Solve for x
1/2x + 7 = 18
Combine 1/2 and x.
x/2+ 7 = 18
Move all terms not containing x to the right side of the equation.
Subtract 7 from both sides of the equation.
x/2= 18 − 7
x/2 = 11
Multiply both sides of the equation by 2.
2 ⋅ x/2 = 2 ⋅ 11
Simplify both sides of the equation.
Cancel the common factor of 2.
x = 2 ⋅ 11
Multiply 2 by 11.
x = 22

Answers
Answer:
x = 35°
∠Q = 127°
∠R = 35°
∠P = 18°
Step-by-step explanation:
x + 2x + 57 + x - 17 = 180 {Angle sum property of triangle}
x + 2x + x +57 -17 = 180 {Combine like terms}
4x + 40 = 180
4x = 180 - 40
4x = 140
x = 140/4
x = 35
∠Q = 2x + 57 = 2*35 + 57 = 70 +57 = 127°
∠R = x = 35°
∠P = x - 17 = 35 - 17 = 18°

Which statements below are ALWAYS TRUE about Rectangles? Choose ALL THAT APPLY.

- Diagonals bisect each other in diagonals are equal in length
- Diagonals bisect each other, but they are NOT equal in length
- Opposite sides are congruent
- All four sides are congruent
- Diagonals bisect 90° angles
- Diagonals DO NOT bisect 90° angles
Answers
3 Answers:
B) Diagonals bisect each other and diagonals are equal in lengthD) The opposite sides are congruentG) Diagonals do not bisect the 90 degree angles==========================================================
Explanation:
Let's go through the answer choices one by one
A) This is false. If the diagonals were perpendicular, then we would have a square. The diagonals are also perpendicular for any rhombus and for any kite. For any non-square rectangle, the diagonals are not perpendicular.B) This is true. The diagonals bisect each other because we're dealing with a parallelogram. Any rectangle is a parallelogram. For any rectangle, the diagonals are equal in length as well. We can use SAS congruence theorem to prove this.C) This is false. The first part is true, but the second part contradicts what choice B is saying.D) This is true. The opposite sides of any rectangle are congruent, and they are parallel. E) This is false. Imagine a really stretched out or elongated rectangle. So not all four sides of a rectangle are the same length. If they were, then we would have a square.F) This is false. The diagonals do not bisect the angles unless we're dealing with a square. Again imagine stretching out a rectangle to make it very elongated. G) This is true since choice F was false.The statements always true about rectangles are Diagonals bisect each other in diagonals are equal in length, Opposite sides are congruent, Diagonals DO NOT bisect 90° angles.
What is Rectangle?Rectangle is a two dimensional figure which has four sides and four angles and all the angles are right angles.
Diagonals are not perpendicular in rectangles. So first statement is wrong.
Diagonals bisect each other in rectangles and the length of the diagonals are equal.
Since the length of diagonals are equal, third statement is wrong.
Opposite sides of a rectangle are equal and are thus congruent.
In a rectangle, only opposite sides are congruent and equal. All the four sides are not equal and are thus not congruent.
Diagonals of a rectangle does not bisect 90° angles.
Hence the correct statements are shown.
