Answer:
Corresponding angle theorem, vertical angle theorem, and the transitive property of congruence.
Step-by-step explanation:
Considering a set of parallel lines cut by a transversal. (Refer the attached image).
Now that lines J and K are parallel, then by "corresponding angle theorem"

By "vertical angle theorem"

Using, "transitive property of congruence"

And that is our required proof. In this whole proof we have used "corresponding angle theorem", "vertical angle theorem", and the "transitive property of congruence".
Answer:
The integer 'A' represents -8.
<u>Answer:</u>
The denominator of a fraction is 4 more than the numerator. The original fraction is 
<u>Solution:</u>
Given that
Denominator of fraction is 4 more than the numerator.
Let’s say numerator of fraction be represented by variable x.
So denominator of a faction as it is four more that numerator will be x + 4
Also given if both decreased by three than simplified result is 

Solving above equation for x
=> 7(x – 3 ) = 6 ( x + 1 )
=> 7x – 21 = 6x + 6
=> 7x – 6x = 6 + 21
=> x = 27
Numerator of fraction = x = 27
Denominator of fraction = x + 4 = 27 + 4 = 31


Hence the original fraction is 
I think it would be 29 students in the larger class
THe answer is the second option because you have to use the pythogorean theorm to fing the 3rd side and multiply your answer by 2 to get the value of x.
