If two chords in a circle are congruent, then they are
A. perpendicular
B. the same distance from the center of the circle
C. parallel
If two chords in a circle are congruent, then they are the same distance from the center of the circle. Then the correct option is B.
What is a circle?It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.
The central angle is double the angle at the periphery that was subtended by the same chords.
Both the extreme points of the chords are connected to the circle. Then the two triangles are formed whose two sides are the radius of the circle that is congruent to each other. Then the triangle will be an isosceles triangle.
And the chord length is also congruent. Then the triangles are congruent to each other by SSS postulates.
If two chords in a circle are congruent, then they are the same distance from the center of the circle. Then the correct option is B.

What is the value of y?
Answer:
option a
Step-by-step explanation: y+y=114 (exterior angle property)
2y=114
y =114/2
y = 57
The measure of angle 'y' in the triangle is 57 degrees.
What is the measure of y in the triangle?The figure in the image is a triangle.
From the diagram:
Angle 1 = y degrees
Angle 2 = y degrees
Angle 3 =?
First, we determine the measure of the third angle.
Since the sum of angles on a straight line equals 180 degrees:
Angle 3 + 114 = 180
Angle 3 = 180 - 114
Angle 3 = 66
Now, the total sum of the interior angles of a triangle equals 180 degrees.
Hence:
Angle 1 + Angle 2 + Angle 3 = 180
y + y + 66 = 180
Collect and add like terms:
2y + 66 = 180
2y = 180 - 66
2y = 114
Divide both sides by 2:
y = 114/2
y = 57°
Therefore, y has a value of 57.
Option A) 57° is the correct answer.

Answer:
We need a non-included side of one triangle
Step-by-step explanation:
By means of the AAS postulate.
The Angle-Angle-Side postulate (AAS) tells us that if two angles and a non-included side of one triangle are congruent to two angles and the corresponding non-included side of another triangle, then the two triangles are congruent.

Step-by-step explanation:
Hello,
the sum of all angles of the triangle at the left must be 180
so the last one is 180 - 80 - 60 = 40
and then the angle at the bottom left of the second triangle is 180 - 40 -72 = 180 - 112 = 68
and then the angle that we have to find is 180 - 64 - 68 = 48

Find the sum of the first 34 terms to the nearest integer
13,19,25
Answer:
3808
Step-by-step explanation:
Given the sequence: 13,19,25
First Term, a=13
Common Difference, d=19-13=25-19=6
Since we have a common difference, the sequence is an arithmetic sequence.
We determine the sum of any nth term of an arithmetic sequence using the formula:
[tex]S_n=\frac{n}{2}[2a+(n-1)d] \\n=34, a=13, d=6\\$Therefore:\\S_{34}=\frac{34}{2}[2(13)+(34-1)*6]\\=17[26+33*6]\\=17[26+198]\\=17*224\\S_{34}=3808[/tex]

f(x) = x ^ 2 + 6x - 4 in vertex form
Answer:y=(x-6)^2-4
Step-by-step explanation:
Answer:
f(x) = (x + 3)² - 13
Step-by-step explanation:
The equation of a parabola in vertex form is
f(x) = a(x - h)² + k
Given
f(x) = x² + 6x - 4
Using the method of completing the square
add/subtract ( half the coefficient of the x- term )² to x² + 6x
f(x) = x² + 2(3)x + 9 - 9 - 4
f(x) = (x + 3)² - 13 ← in vertex form

Answer: 16 units squared
If there is units for the grid, use those as your measurements, but if not, use each box to equal 1.
You can solve this by finding the area of a rectangle bigger than the original shape (straighten out diagonal lines)
Once you do this, count the units (boxes) of the length and width of the rectangle (5 X 4)
You would then multiply the length and width to find the area of the rectangle
5 * 4 = 20
..... But you still need to find the parallelogram so you have to subtract the space you filled in
Since the shape is a parallelogram, you can tell that the area filled in is equal on both sides, and when put together, they form a smaller rectangle
This rectangle would be 1 X 4
1 * 4 = 4
Then you have to subtract the smaller rectangle from the larger rectangle
20 - 4 = 16
