Answer:

  A  Alternate interior angles of parallel lines are congruent

Step-by-step explanation:

The referenced angles (1, A), (3, C) are alternate interior angles, not corresponding or exterior. The symmetric property does not apply. The only answer choice with any applicability is the one shown above. (It is also the right choice.)

Answer:

<h2>A . Alternate interior angles of parallel lines are congruent</h2>

Step-by-step explanation:

If you observe the image, the statement that Janet wants to justify is

\angle 1 \cong \angle A

\angle 3 \cong \angle C

According to the given graph, these angles are inside parallels because DE \parallel AC by given, and these angles are at different sides of the transversals BA and BC, those position define Alternate Interior Angles, which by theorem  they are congruent.

Therefore, the right reason of such congruence is

<em> A . Alternate interior angles of parallel lines are congruent.</em>

What value(s) of x make the equation x2 - 18x + 81 = 0 true?
mel-nik [20]
We can factorise this to get (x-9)(x-9). To find the value, each bracket needs to equal 0, so the value would be x=9

Ven Diagrams with union and intersection problems shading in diagram
Anika [276]

Answer:

4 types of questions one will be to read, 2nd will be to subtract, one will be to add, the next will be to find missing numbers each are expressed below.

Step-by-step explanation:

This is a two-circle Venn diagram. The 1st circle is A, and the 2nd circle is B. The complete Venn diagram represents the union of A and B, or A ∪ B.

Just intersect is A ∩ B

Just intersect B ∩ A

A∩B=   A∩B={2}  differs significantly from below.

A  small ∁

 (sometimes denoted as ~A or ¬A)

is pronounced as: "A complement" (or "not A", for the other notations)

means: the new set gets everything that is in the universe but is outside of A; it's okay if the element is in B, just so long as it is not also in A

in terms of the elements: {1, 2, 3, 4} – {1, 2}

my answer:  = A ∁ ={3,4}

A – B (or A \ B)in terms of the elements: {1, 2} – {2, 3}

A – B = {1}

A∪B)=¬(A∪B)in terms of the elements: = {1, 2, 3, 4} – {2}

in terms of the elements: {1, 2, 3, 4} – ({1, 2} ∪ {2, 3}) = {1, 2, 3, 4} – {1, 2, 3}

(4) elements here are just the remainder my answer: my answer:(A∪B)={4}

Please solve this...question..it may come in my exam.#math problem fast solve it and help me​
ehidna [41]

Answer:

n + y

Step-by-step explanation:

a² - b² = (a +b)(a - b)

\frac{n^{2}-y^{2}}{n+y} ÷ \frac{n - y }{n + y } = \frac{(n + y)(n - y)}{(n + y)}*\frac{(n + y)}{(n - y)}\\\\    

    { (n + y) in the denominator and numerator will be cancelled ;

       (n - y) in the denominator and numerator will be cancelled

                    = n + y
