What is an angle?In mathematics and geometry, an angle is a measure of the amount of rotation or turn between two lines or line segments that meet at a common endpoint, called the vertex of the angle.
Angles are typically measured in degrees (°) or radians (rad).
A full rotation around a point is 360 degrees or 2π radians.

Given: circle: k(O), m∠A = 101° m∠L = 79°, m LK = 122° Find: m AJ
Answer:
m arc AJ = 78°
Step-by-step explanation:
If angle A is 101° that means arc LKJ is 202° (the measure of an arc that an inscribed angle intercepts is twice the angle measure). If arc LKJ is 202° and arc LK is 122°, then arc KJ is 80° (m arc LK + m arc KJ = m arc LKJ).
If angle L is 79°, then the m arc AJK = 158° (the measure of an arc that an inscribed angle intercepts is twice the angle measure). If m arc AJK = 158° and m arc KJ is 80°, then the m arc AJ is 158 - 80 = 78º

What is the volume of the following triangular prism?

4 cm
cubic centimeters. You must submit your neat and organized work once you have submitted the test.
Write only the number.
10 points need fast
Answer:
[tex]V=150cm^3[/tex]
Step-by-step explanation:
First we need to find area of the triangle with a base of 4 cm and a height of 5cm, and then multiply that by the length of the prism of 15cm.
The area of the triangle is given by the formula:
[tex]A_T=\frac{bh}{2}[/tex]
where b is the base: [tex]b=4cm[/tex] and h is the height: [tex]h=5cm[/tex]
thus, in this case we have:
[tex]A_T=\frac{(4cm)(5cm)}{2}\\ \\A_T=\frac{20cm^2}{2} \\\\A_T=10cm^2[/tex]
And now, the volume will be the area of the triangle multiplied by the length [tex]l=15cm[/tex] of the prism:
[tex]V=A_T*l[/tex]
Substituting the known values:
[tex]V=10cm^2*15cm\\V=150cm^3[/tex]
The volume in cubic centimeters is 150.

The coordinates of D'E'F' after reflection are,
D' = (0, - 3)
E' = (1, 0)
F' = (2, - 1)
We have to given that,
Triangle DEF has vertex coordinates D(0, -3), E(-1,0), and F(-2,-1).
Here, Triangle DEF is reflected across the y-axis.
The rule for a reflection over the y -axis is,
(x, y) → (- x, y)
Hence, the coordinates of D'E'F' after reflection is,
D' = (0, - 3)
E' = (- (- 1), 0) = (1, 0)
F' = (- (- 2), (- 1)) = (2, - 1)

3) The sum and the difference of the LCM and GCD of two numbers are 312 and 264 respectively. Find the numbers if their sum is 168.
Answer:
The numbers are 72 and 96.
Step-by-step explanation:
LCM + GCF = 312
LCM - GCF = 264
2*LCM = 576
LCM = 576/2 = 288
HCF = 312–288 = 24
The product of two numbers = HCF*LCM
Let the numbers be x and (168-x)
x(168-x) = 24*288 = 6912
x^2–168x+6912 = 0
x = [168 +(168^2 -4*6912)^0.5]/2
= [168 +(28224–27648)^0.5]/2
= [168 + 576^0.5]/2
= (168+24}/2
= 192/2
= 96 and the other number is 168–96 = 72.

The height of a parallelogram is three times its base. If the area of the parallelogram is 675 square inches, find its base and height.
Which of these choices are correct?
b = 25 in & h = 75 in
b = 75 in & h = 225 in
b = 45 in & h = 135 in
b = 25 in & h = 12.5 in
Answer:
Step-by-step explanation:
let base be x and height be 3x
we know area of parallelogram is
base*height
ie x*3x=675
3x^2=675
x^2=675/3
x^2=225
x= square root of 225
x=15
therefore base =15
height = 45
A spinner has four equal sections, with one letter from the word "MATH" in each section.
Type your response in each blank below.
1. You spin the spinner 20 times. About how many times do you expect it will land on A?
2. You spin the spinner 80 times. About how many times do you expect it will land on something other than A?
Explain your reasoning.
Answer:
1. 5 times
2. 60 times
Step-by-step explanation:
there is only one a so its 1/4 times 20 and 4 because that is the total
20/4= 5
there is 3 because there is letters that are not a
3/4 times 80
240/4
1. The number of times expected that should be landed on A should be 5 times.
2. The number of times expected should be 60 times.
Calculation of the number of times:1. Since A spinner has four equal sections, with one letter from the word "MATH" in each section.
So, here the number of times should be
= [tex]20\div 4[/tex]
= 5
2. The number of times should be

Step-by-step explanation:
Let's see. There is a missing side. Let's call that x. However, we know what the other sides are!
This is how we do it.
We know the largest side's length., 172.
Since we know the other sides, we can subtract their length from 172.
172-57-51-31=33
x=33
So now add the sides!

The measure of central angle MNL is π radians, and the measure of the entire circle is 2π radians. The ratio of the measure of the central angle to the entire circle measure is . The area of the entire circle is π units2. The area of the sector is π units2.
Answer:
The answer is "The calculated ratio of the central angle to the entire circle is 1:2".
Step-by-step explanation:
Let,
MNL angle [tex]= \pi[/tex]
So, the entire circle is [tex]= 2\pi[/tex]
The ratio of the central angle to the entire circle is:

find points of discontinuity y=x-8/x^2+6x-7
Answer:
Step-by-step explanation:
You'll need to use parentheses here to remove ambiguity regarding what's in your denominators:
x - 8 x - 8
y = ------------------ = -----------------
x^2 + 6x - 7 (x + 7)(x - 1)
This last result becomes undefined at x = -7 and x = 1, and thus its graph is discontinuous at those x- values.
The points of discontinuity is x = -7, x = 1
Use parentheses to remove ambiguity considering the denominators
[tex]y=x-8/x^{2} +6x-7[/tex]
= x-8 ÷ (x+7)(x-1)
The result becomes undefined at x = -7
and x = 1,
thus its graph is discontinuous at those x values.
Therefore the points of discontinuity is x =-7 and x = 1.
