State the postulate or theorem you would use to prove each pair of triangles congruent. If the triangles cannot be proved congruent, pick not possible
The triangles can be proven similar by the congruent theorem of triangles
What are Congruent Triangles?
Transformations change the size or position of shapes. Congruent shapes are identical, but may be reflected, rotated or translated. Scale factors can increase or decrease the size of a shape. Congruent Triangles simply mean the triangles that possess the same size and shape
The three sides are equal (SSS: side, side, side)
Two angles are the same and a corresponding side is the same (ASA: angle, side, angle)
Two sides are equal and the angle between the two sides is equal (SAS: side, angle, side)
A right angle, the hypotenuse and a corresponding side are equal (RHS, right angle, hypotenuse, side)
Given data ,
Let the two triangles be ABC and DEF
Now , the two triangles will be similar if
The three sides are equal
So , AB = BC = CD and
DE = EF = FD
And the two triangles are congruent if
By ASA theorem - two angles are the same and a corresponding side is the same
And ,
By SAS theorem : Two sides are equal and the angle between the two sides is equal
And ,
By RHS theorem : A right angle, the hypotenuse and a corresponding side are equal
Hence , the triangles ABC and DEF is similar ΔABC ≅ ΔDEF

1 2/5 x 1 2/5 as a fraction mixed fraction
Answer:
1 24/25 or one and twenty-four twenty-fifths (in word form).
Step-by-step explanation:
This would be the answer since, we firstly have to convert the mixed fractions into improper fractions. 7/5*7/5, which equals to 49/25. In simplified form it would be 1 2/25.
1 2/5=7/5
7/5*7/5= 49/25 or 1 24/25.
Anyhow, the answer is 1 24/25
The simplified mixed fraction for the given fraction is [tex]24\frac{1}{2}[/tex]
What are mixed fractions?A fraction represented with its quotient and remainder is a mixed fraction, a mixed fraction is a combination of a whole number and a proper fraction.
Given that a fraction [tex]1\frac{2}{5}[/tex] × [tex]1\frac{2}{5}[/tex]
We need to simply it in a mixed fraction,
[tex]1\frac{2}{5}[/tex] × [tex]1\frac{2}{5}[/tex]
= 7/2 × 7/2

Kayla is thinking of a 3-digit number.
* It is divisible by 18.
* It is a palindrome (It reads the same left-to-right as it does right-to-left, like 252 and 848).
* It is one less than a multiple of 5.
What is Kayla’s number?
Answer:
kaylas thinking of the number 414
Step-by-step explanation:
414 is divisable by 18 (414 divided by 23)
414 is palindrome
414 is one less than a multiple of 5 (415)
Answer:
414
Step-by-step explanation:
The last digit must be 4 or 9 since it is one less than a multiple of five. Then, it says the number must be divisible by 18, and 18 = 2x9. Only 4 is divisible by 2, so four must be the last digit. Since it's a palindrome, the first digit must also be four. Since it also has to be divisible by nine, 4 + 4 = 8, and 8 + 1 = 9.

What is a right-angle triangle?It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.
A tree casts a shadow 21 m long.
The angle of elevation of the sun is 51°.
Let h be the height of tree.
Then the height of the tree will be
tan 51° = h / 21
h = 25.93 m

Step-by-step explanation:
After taking a 70 point test, a student guesses that he got 65 points correct. Later he finds out he got 67 points
correct. Calculate the percent error of his guess to 3sf.
Answer:
Percent error = 4.29%
Step-by-step explanation:
Percent error can be defined as a measure of the extent to which an experimental value differs from the theoretical value.
Mathematically, it is given by this expression;
[tex] Percent \; error = \frac {experimental \;value - theoretical \; value}{ theoretical \;value} *100[/tex]
Given the following data;
Experimental value = 67
Theoretical value = 70
Substituting into the equation, we have;
[tex] Percent \; error = \frac {67 - 70 }{ 70} *100[/tex]
[tex] Percent \; error = \frac {3}{70} *100[/tex]
[tex] Percent \; error = 0.04286 *100[/tex]
Percent error = 4.29%

Answer:
$100.02
Step-by-step explanation:
*Sales tax is always applied after the discount/coupon
1. Find how much Hana had spent on pants. Since she had bought 2 pairs of pants, and they are $26.59 each, we would have to multiply 26.59 by 2. So,
26.59 times 2 is 53.18.
Hana spent $53.18 on pants
2. Find how much Hana had spent on a coat. Since she had bought 1 coat, and they are $49.00 each, we would have to multiply 49.00 by 1. So,
49.00 times 1 is 49.
Hanna spent $49 on coats
3. Find how much Hana spent on clothes. Since she spent $53.18 on pants and $49 on coats, we would have to add 53.18 and 49. So,
53.18+49=102.18
Hanna spent $102.18 on clothes
4. Find how much Hana "spent" after using the coupon. Since the problem says the coupon helps Hana save $10, we need to subtract 10 from 102.18(the total amount of money Hana spent on clothes before using the coupon). So,
102.18-10=92.18
Hanna "spent" $92.18 on clothes after using the coupon
5. Find how much was the total purchase. Sales Tax is the amount of money that needs to be added to the price. Since the price is $92.18 and the sales tax is $7.84, we need to add 7.84 to 92.18. So,
7.84+92.18=100.02
The total purchase is $100.02

Which term best describes the two lines represented by the equations below?
Answer:
Option (2)
Step-by-step explanation:
Equations of the lines have bee given as,
y = [tex]\frac{4}{3}x-5[/tex]
y = [tex]\frac{4}{3}x+3[/tex]
Both the equations are in the slope intercept form. (y = mx + b)
They have same slopes but different y-intercepts.
Same slopes of the equations define the lines to be the parallel lines.
Therefore, Option (2) will be the correct option.
