It is Given that two lines segment, AC and BD bisect each other at C.
The missing statement is ∠ACB ≅ ∠ECD
What is the congruent triangle?Two triangles are said to be congruent if the length of the sides is equal, a measure of the angles are equal and they can be superimposed.
Given two lines segment, AC and BD bisect each other at C.
We have to prove that ΔACB ≅ ΔECD
In triangle ACB and ECD
AC=CE (Given)
BC=CD (Given)
so, as seen in options the angle ∠ACB ≅ ∠ECD due to vertically opposite angles

determine the solution to the system of equations g(x)=3x+2, f(x)=x-4+2
The solution to the given system of equations is the point (1, 5).
How to solve the system of equations?
Here we have the system of equations:
g(x) = 3x + 2
f(x) = |x - 4| + 2
To solve this, first you can see where the graphs intercept on the graph (the intercept point is the solution to the system)
But we can also solve it analytically. To do it, we have:
g(x) = f(x)
3x + 2 = |x - 4| + 2
3x = |x - 4|
Notice that the only solution of the above equation is x = 1, so we know that it is the x-value of the solution.
To get the y-value, we just evaluate one of the two given functions on x = 1.
f(1) = |1 - 4| + 2= 3 + 2 = 5
Then the solution to the system is the point (1, 5).

In 2018 there were 238 Republicans and 201 Democrats in the House of Representatives. Find the percentage of Democrats in the House of Representatives in 2018
Answer:
45.7% or if rounded, 46%
Step-by-step explanation:
1st, you add up the total of people in the House of Representatives.
238+201=439
Then divide the number of Democrats 201 by the total number 439 to get .457 which is 45.7% or if you need to round 46%
To double check, multiply the total number 439 X 45.7% to get 200.6

A circle has a circumference of 3 meters. What is the circle's radius?
Use 3.14 for pi and round your answer to the nearest tenth.
PLS HELP!!! No links pls and ty <3
Formula for the circumference of a circle = pi x 2 x radius
Circumference = 3
pi = 3.14
radius = r
---To find the radius, we will need to solve for it. Start by plugging in what we know.
3 = 3.14 x 2 x r
---Simplify by multiplying 3.14 by 2
3 = 6.28 x r
---Divide both sides by 6.28 to solve for r
r = 3 / 6.28 = 0.4777
---Round the decimal to the nearest tenth
r = 0.5
Hope this helps!
r=0.5
Solution:Circumference of a circle - C=2πrPlug in the values we are given:3=2πrSimplify:3=6.3rDivide both sides by 6.3:r=0.5Hope it helps.

Two angles are supplementary. If angle A is five times the sum of the angle B plus 7. 2, what is angle B
Answer:
Angle B = 24°
Step-by-step explanation:
Given:
Angles are supplementary Angle A is 5 times the sum of angle B plus 7.2that means, Angle A = 5 ( Angle B + 7.2 )
Now,
Let Angle B = x (say)
•.• Angle A = 5 ( x + 7.2 )
Supplementary angles are a pair of angles that make sum of 180° .Therefore, As it is given that the angles are supplementary , the sum of Angle A and Angle B will be equal to 180°.
Angle A + Angle B = 180°
[tex]⇢x + 5(x + 7.2) = 180[/tex]
[tex]⇢x + 5x + 36 = 180[/tex]
[tex]⇢6x = 180 - 36[/tex]
[tex]⇢6x = 144[/tex]
[tex]⇢x = \frac{144}{6} [/tex]
[tex]⇢ \boxed{x = 24}[/tex]Now, substituting the value of x. . .
Angle B = 24°Angle A = 5( 24+ 7.2 ) = 5( 31.2 ) = 156°Thus, Angle B comes out 24°
Find the unknown side length, x. Write your answer in simplest radical form.

C. 16/5
D. 16 V13
Answer:
C
Step-by-step explanation:
Use the pythagorean theorem.
32^2+b^2=48^2
1024+b^2=2304
Subtract 1024
b^2=1280
Square root
b=sqrt(1280)
Now simplify sqrt(1280)
sqrt(1280) = sqrt(256*5)
You can take the square root of 256 since it is a perfect square so take it out of the radical.
sqrt(256*5)=16sqrt(5)
So the answer is c, 16[tex]\sqrt{5}[/tex]
Answer:
C. 16/5
Step-by-step explanation:
pythagorean theorem
a^2 + b^2 = c^2
divide 48 and 32 by 16
a= 2 c= 3
4 + b^2 = 9
b^2 = 5
b = √5
then multiply 16 with √5

A rectangle with proportions close to the Golden Ratio of approximately 1:1.618 is believed to be aesthetically pleasing.
What is the golden rectangle?A rectangle with sides that are in the golden ratio, or roughly 1:1.618, is referred to as a golden rectangle. This ratio has been employed in art, architecture, and design for ages since it is seen to be aesthetically beautiful.
To build a golden rectangle, start with a square and then add a smaller square to one of its sides to form a rectangle. The smaller rectangle is then used to repeat this procedure until you obtain a rectangle whose sides are in the golden ratio.
The layout of credit cards is one instance of a situation in real life that makes use of a golden rectangle. Golden rectangles are a popular shape for credit cards because of their attractive proportions and visual balance. A golden rectangle may also be used in credit card designs to help the card stand out from other cards and be simpler to recognize.

a. How can Kiran know for sure that Andre's
solution is incorrect?
b. Describe Andre's error and explain how to
correct his work.
Answer:
Step-by-step explanation:
Kiran can know for sure that it is incorrect by substituting x with 1/4
Solving for the equation gives 4(1/4 + 3) = 7
distributing gives 1 + 3 = 7
obviously this is incorrect
b)
Andre's error is that he didnt distribute 7
Distributing 7 results in
4x + 12 = 7
then subtracting 12 from both sides
4x = -5
x = -5/4
Answer:
x=-1.25
Step-by-step explanation:
well he was wrong about the 4x = 1.

4x+12=7 1. - 12 on both sides
4x=-5 2. 4 on both sides
