Triangles J K L and M N R are shown.
In the diagram, ∠J ≅ ∠M and JL ≅ MR. What additional information is needed to show ΔJKL ≅ △MNR by SAS?
KL ≅ NR
∠L ≅ ∠R
∠K ≅ ∠N
JK ≅ MN
Answer:
JK ≅ MN
Step-by-step explanation:
SAS states that any two sides of the angle and the angle itself, if , of two triangles are equal the two triangles are equal.
It is given that ∠J ≅ ∠M and JL ≅ MR i.e an angle and a side are equal. We need one more side to prove that the two triangles are equal.
If we look at the diagram closely we see that the angles J and M are formed by the sides JK & JL and MN& MR.
It is given that JL ≅ MR so we are left with JK ≅ MN
The additional information needed prove that ΔJKL ≅ ΔMNR by SAS Congruence Theorem is: D. JK ≅ MN
Recall:
The SAS Congruence Theorem proves that two triangles are congruent to each other if they have two pairs of congruent sides and a pair of included congruent angles.The image attached below shows ΔJKL and ΔMNR where we are given the following:
∠J ≅ ∠M (one pair of congruent angles).
JL ≅ MR (one pair of congruent sides).
Therefore, the additional information needed prove that ΔJKL ≅ ΔMNR by SAS Congruence Theorem is: D. JK ≅ MN

In a unit circle, ø = 2pi radians What is the terminal point?
A. (0,1).
B. (0, -1)
C. (-1,0)
D. (1,0)
Answer:
The terminal point is (1, 0) ⇒ D
Step-by-step explanation:
In the unit circle, Ф is the angle between the terminal side and the positive part of the x-xis
The terminal point on the positive part of the x-axis is (1, 0),which means Ф = 0 or 2π radians and cosФ = 1, sinФ = 0The terminal point on the positive part of the y-axis is (0, 1),which means Ф = [tex]\frac{\pi }{2}[/tex] radians and cosФ = 0, sinФ = 1The terminal point on the negative part of the x-axis is (-1, 0),which means Ф = π radians and cosФ = -1, sinФ = 0The terminal point on the negative part of the y-axis is (0, -1),which means Ф = [tex]\frac{3\pi }{2}[/tex] radians and cosФ = 0, sinФ = -1In a unit circle
∵ Ф = 2π radians
→ By using the 1st rule above
∴ The terminal point is (1, 0)
Answer:

A turtle can crawl up to 120 feet per hour. What is this speed in inches per minute?
Answer:
It can crawl 24 inches in 1 minute.
Step-by-step explanation:
1. We know 1 ft = 12 in, so 120 ft = 1,440 in.
2. If the turtle can crawl 1440 inches in 1 hour, that's equivalent to crawling 1440 inches in 60 minutes.
3. we can write this as a fraction and then multiply the denominator 60 by itself to find how many inches per minute the turtle can crawl.
4. 1440/60 ×60/60 =24/1
The sum of the digits of a three-digit number is 12. The tens digit, t, is 2 more than the hundreds digit, h. The units digit, u, is equal to the sum of the tens and hundreds digits. What is the number?
Answer:
so the equation would be
u+t+h=12
lets break it down
we know that t is equal to
h+ 2
and we know that u is equal to
h+t
okay so first we need to focus on finding one of the units then we can find the next ones
so lets find h first,
with the equations we found h is involved in all of them so we can use them in the equation that equals 12 ( ill make it easier for you and make all of the units equal to their equation including h)
u= h+t
h+2=t
t= h+2
h=h
u= h+h+2
so lets put it together
(h+h+2)+(h)+(h+2)=12
4h+4=12
-4 -4
4h=8
/4 /4
h=2
okay now using our other equations lets find t and u
h+2=t
2+2=t
4=t
h+t=u
2+4=u
6=u
now lets check our answers
u+t+h
6+4+2=12
10+2=12
12=12
so now that we know the values lets put them into their places in the number
uth
u=6
t=4
h=2

Mrs Wall usually buys 12 pints of milk each week and pays her milkman £3.72. One week she had visitors and ordered an extra 3 pints. How much was her bill?
Answer:
£4.65 is her bill
Step-by-step explanation:
Here, we firstly need to calculate the unit price of a pint
Mathematically, in this case, that will be 3.72/12 = 0.31
ordering 3 extra pints means she would be buying a total 15
The price of this will be;
0.31 * 15 = £4.65

Given :
cos x = 1.7/2 .
Also, x is an acute angle.
To Find :
The value of angle x.
Solution :
cos x = 1.7/2
Applying cos inverse both the sides, we get :
[tex]cos ^{-1} (cos\ x ) = cos^{-1} \dfrac{1.7}{2}\\\\x = cos^{-1} \dfrac{1.7}{2}[/tex]
Calculating the value of [tex]cos ^{-1} \dfrac{1.7}{2}[/tex] from calculator, we get :
x = 31.79°
Therefore, the acute angle x is 31.79°.

1-1 Item 15 The nutrition facts label on a container of dry roasted cashews indicates there are 161 calories in 28 grams. You eat 9 cashews totaling 12 grams. a. How many calories do you consume? You consume calories. b. How many cashews are in one serving? There are cashews in one serving.
Answer:
69 calories
Step-by-step explanation:
Given that :
Number of calories in 28 grams = 161
9 cashews = 12 grams
Number of calories consumed :
28 grams = 161 calories
12 grams = x
Cross multiply :
28x = 161 * 12
28x = 1932
x = 69 calories

Determine any data values that are missing from the table, assuming that the data represent a linear function.
Answer:
c. 14
Step-by-step explanation:
Let the missing y value be y2.
If the data represent a linear function, then:
[tex] \frac{6 - 2}{2 - 1} = \frac{y_2 - 6}{4 - 2} [/tex]
[tex] \frac{4}{1} = \frac{y_2 - 6}{2} [/tex]
[tex] 4 = \frac{y_2 - 6}{2} [/tex]
Multiply both sides by 2
[tex] 4 \times 2 = \frac{y_2 - 6}{2} \times 2 [/tex]
[tex] 8 = y_2 - 6 [/tex]
Add 6 to both sides
[tex] 8 + 6 = y_2 - 6 + 6 [/tex]
[tex] 14 = y_2 [/tex]
The missing value is 14

Need help with this question. I will give Brainliest!
Answer:
See below
Step-by-step explanation:
a) The vertex is (0,2) so the standard form equation is (x-0)^2=4p(y-2). Since p=1/(4a) and a=1/8, then p=1/(4(1/8))=1/(1/2)=2. This makes the equation now x^2=8(y-2). Given the focus point for a vertical parabola is (h,k+p) then the focus point is (0,2+2) which is (0,4)

Javine says, "To multiply by 1000, I just add three zeros." Kian says, "I times by 10, then times by 10 and times by 10 again." Do you agree with Javine and Kian's methods for multiplying by 1000? Explain your thinking.
Answer:
Kian's method is correct.
Step-by-step explanation:
Javine says, "To multiply by 1000, I just add three zeros." He is incorrect.
Kian says, "I times by 10, then times by 10 and times by 10 again. When he multiply 1 by 10, it becomes 10. Then if he again multiply by 10, it becomes 10×10 = 100. And at last when he multiply again 10, it becomes 100×10 = 1000. It means Kian's methods for multiplying by 1000 is correct.
There are only red counters and blue counters in a bag. The ratio of red counters to blue counters is 5:4. There are 27 blue counters. How many red counters are there?
Answer:
33.75 red counters
Step-by-step explanation:
Given the ratio of the red counters to blue counters as 5:4. The total ratio will be 5 + 4 = 9
If there are 27 blue counters in the bag, the total amount of counters there will be gotten using the expression;
4/9 * x = 27
x is the total counter in the bag.
4x/9 = 27
4x = 9*27
x = (9*27)/4
x = 60.75
The amount of red counters there will be
red counters = Total - blue counter
red counter = 60.75 - 27
red counter = 33.75 red counters

ΔHKJ and ΔLNP are similar triangle due to equal pair of corresponding angles .
What are Similar Triangles?Similar triangles are defined as two triangles with the same shape, equal pair of corresponding angles, and the same ratio of the corresponding sides.
Given,
m∠H = 30°
m∠J=50°
m∠P=50°
m∠N=100°
In triangle ΔHKJ
m∠H = 30°
m∠J=50°
m∠K= 180°- (m∠H+m∠J) = 180°-(30°+50°)
m∠K= 100°
In ΔHKJ and ΔLNP,
m∠J = m∠P= 50°
m∠K= m∠N= 100°
According to Angle-Angle (AA) rule, two triangles are said to be similar if two angles in one particular triangle are equal to two angles of another triangle.
Thus, ΔHKJ and ΔLNP are similar triangle due to equal pair of corresponding angles.
Hence, ΔHKJ ~ ΔLNP
