which of the following theorems verifies that DEF=XYZ? a)AA b) LL c) HA d)HL
Answer:
is it AA..
I have no idea what to do how...
The theorems that verifies the ΔDEF ≅ ΔXYZ by SAS congruency Criteria.
What is Congruency?Congruent figures have sides that are the same length and angles that are the same measurement. In other words, congruent figures are those in which one figure superimposes another. Even when twisted or flipped, they perfectly fit together.
We have, two triangles DEF and XYZ.
Now, from the two triangle
EF = XY (Given)
DF = XZ (Given)
<EFD = < YZX (Each 90)

A car is traveling at a constant velocity. After two hours the car has traveled 110 miles.
After four hours the car has traveled 220 miles. Assuming a linear equation fits this
situation, find the distance that the car will travel after five hours.
Answer:
As the velocity is constant,
Distance covered in n hours = n × distance covered in 1 hr
Distance covered in 7 hrs = 7 × 110 = 770 miles

Use the right triangle ABC. The figure is for reference only and is not drawn to scale. If AC = 16 cm and AB = 34 cm what is the length BC?
Answer:
AB = 34 and AC = 16
BC^2 = 34^2 - 16^2
BC^2 = 1,156 - 256

1.38 is the mean of the amount of rainfall over the course of the week
Answer:
1.4 inches (1 decimal place)
Step-by-step explanation:
To calculate the mean you get the sum of all the terms required and divide by the number of terms you summed up.
All of the terms in the table sum up to 29/3. 29/3 divided by 7 (number of days in a week) = 1.3809..., which you can round to 1.4 inches

plz help me. its " joseph runs 2/3 of a mile in 8 minutes. if joseph runs at that speed, how long will it take him to run 1 mile. and show your work". PLZ HELP ME ILL GIVE U 20 POINTS.
Answer:
He runs 2/3 mile in 8 mins, he runs one mile in 12 mins
It will take Joseph 12minutes to run 1 mile
Speed is defined as the ratio of the distance covered to the time taken.
If Joseph runs 2/3 of a mile in 8 minutes, then;
[tex]\frac{2}{3} miles = 8minutes[/tex]
In order to calculate the time it will take Joseph to run 1 mile, we can write:
[tex]1mile=x[/tex]
Divide both expressions
[tex]\dfrac{\frac{2}{3} }{1} =\dfrac{8}{x} \\\dfrac{2}{3}=\dfrac{8}{x}[/tex]
Cross multiply
[tex]2x=3 \times 8\\2x=24\\x=\frac{24}{2} \\x=12minutes[/tex]
This shows that it will take Joseph 12minutes to run 1 mile.

Explain, with a test, why the two triangles in each figure are similar. Find the
unknown lengths.
Answer:
x = 3, y = 6
Step-by-step explanation:
In the figure attached,
If ΔADE and ΔABC are similar triangles, their corresponding sides will be in the same ratio.
By this property,
[tex]\frac{AB}{AD}=\frac{AC}{AE}=\frac{BC}{DE}[/tex]
[tex]\frac{AB}{AD}=\frac{AC}{AE}[/tex]
[tex]\frac{AD+BD}{AD}=\frac{AE+EC}{AE}[/tex]
[tex]\frac{3}{2}=\frac{x+1.5}{x}[/tex]
3x = 2x + 3
3x - 2x = 3
x = 3
Similarly, [tex]\frac{AB}{AD}=\frac{BC}{DE}[/tex]
[tex]\frac{3}{2}=\frac{y}{4}[/tex]
y = [tex]\frac{3\times 4}{2}[/tex]

What is the value of X in the figure?
Answer:
x = 360/7
Step-by-step explanation:
the sum of 3x and 2/4x is supposed to be 180 degrees.
1.- write it as an equation.
3x + 1/2x = 180
2.- Combine like terms.
3x + 1/2x = 7/2x
7/2x = 180
3.- divide.
180 / 7/2 = 360/7

Answer:
Step-by-step explanation:
It is mandatory (required) to use " ^ " for exponentiation:
(3x – 5)^2 = 4
Taking the square root of both sides, we get
3x - 5 = ±2, or
3x = 5 ±2, or
(a) 3x = 7 => x = 7/3, and
(b) 3x = 3, or x = 1

Select all that are measures of angles that are coterminal with a -50° angle.
-770°
-530°
-410°
50°
310°
360°
410°
670°
Answer: -770, -410, 310, 670 degrees
Step-by-step explanation:
Coterminal angles are angles that are have the same sides ... they are essentially the same angle, but are, for example, rotated an extra 360 degrees.
You can add/subtract 360 degrees to check if angles are coterminal:
-770 = -50 - 360 - 360 -- YES, it is coterminal with a -50 degree angle.
-530 [tex]\neq[/tex] -50 - 360 ... -- NO
-410 = -50 - 360 -- YES
50 [tex]\neq[/tex] -50 + 360 ... -- NO
310 = -50 + 360 -- YES
360 [tex]\neq[/tex] -50 + 360 ... -- NO
410 [tex]\neq[/tex] -50 + 360 ... -- NO
670 = -50 + 360 + 360 -- YES

what is the missing constant term in the perfect sqaure that starts with x^2 - 4x
Answer:
The expression is; x^2 – 4c + 4
Step-by-step explanation:
For the expression to be a perfect square, let us say the constant term should be assigned as ⇒ c;
This creates of following expression;
x^2 - 4x + c
In order to be a perfect square, the discriminant needs to be zero ;
( - 4 )^2 - 4 * ( 1 )c = 0 ,
16 – 4c = 0 ,
4c = 16 ,
c = 4 ,
Solution; The expression is, therefore; x^2 – 4c + 4
