Answers

Explanation:

To get to the desired conclusion, you will want to make use of CPCTC and the fact that triangle AXB is congruent to triangle CYD. In order to show those two right triangles are congruent, it is sufficient to claim congruence of their hypotenuses and one internal acute angle (HA congruence). The corresponding internal angles are alternate interior angles where a transversal (BD) crosses parallel lines (AB║CD). It's tedious, but not terribly difficult.

__

Statement . . . . Reason

1. Congruent segment pairs are (AB, CD), (AD, BC) . . . . given

2. Perpendicular segment pairs are (AX, BD), (CY, BD) . . . . given

3. ABCD is a parallelogram . . . . definition of parallelogram (opposite sides are the same length)

4. AB ║ CD . . . . definition of parallelogram (opposite sides are parallel)

5. ∠ABX ≅ ∠CDY . . . . alternate interior angles at BD

6. ΔAXB and ΔCYD are right triangles . . . . definition of right triangle (angles at X, Y are 90°)

7. ΔAXB ≅ ΔCYD . . . . HA congruence postulate (AB, CD are the hypotenuses)

8. AX ≅ CY . . . . CPCTC

Additional comment

A lot of proof has to do with working backward, answering the question, "How do I know ...?" The beginning paragraph in this answer attempts to show you the answers to those questions.

This proof works with the smaller triangles AXB and CYD. You could do the same proof with the larger triangles AXD and CYB. For that, you'd have to claim that AD║BC.

Answer:

Given equation :

[tex]{\qquad \sf \dashrightarrow{ 56= 7v + v }}[/tex]

We can rewrite the equation as :

[tex]{\qquad \sf \dashrightarrow{ 7v + v = 56 }}[/tex]

Adding like terms :

[tex]{\qquad \sf \dashrightarrow{ 8v = 56 }}[/tex]

Dividing both sides by 8 :

[tex]{\qquad \sf \dashrightarrow{ \dfrac{8v}{8} = \dfrac{56}{8} }}[/tex]

Suppose that a and b are nonzero real numbers, and
that the equation x² + ax + b = 0 has solutions a
and b. Then the pair (a, b) is

Answers

The equation has two solutions. Means Discriminant means b^2-4ac >0

Here b = a.

a = 1

c = b

a^2 - 4b >0

a=2

b= -1

then a^2 - 4b > 0 = 4+4 > 0

therefore its 2, -1

The pair (a, b) represents the sum and product of the roots of the quadratic equation x² + ax + b = 0.

We have,

Given that the equation x² + ax + b = 0 has solutions a and b, the sum and product of the roots (a and b) can be related to the coefficients of the quadratic equation.

The sum of the roots of a quadratic equation is given by:

Sum of roots = -coefficient of x / coefficient of x² = -a

The product of the roots of a quadratic equation is given by:

Product of roots = constant term / coefficient of x² = b

From the given information, we have:

The sum of roots = a

Product of roots = b

Thus,

The pair (a, b) represents the sum and product of the roots of the quadratic equation x² + ax + b = 0.

Answers

Answer:

m∠C = 75°

Step-by-step explanation:

Theorem:

The consecutive angles of a parallelogram are supplementary (sum to 180°).

⇒ m∠D + m∠E = 180°

⇒ (7x + 21) + (15 + 5x) = 180

⇒ 7x + 21 + 15 + 5x = 180

⇒ 12x + 36 = 180

⇒ 12x = 144

⇒ x = 12

Theorem:

Opposite angles of a parallelogram are equal.

⇒ m∠C = m∠E

⇒ m∠C = 15 + 5x

Substituting found value of x:

⇒ m∠C = 15 + 5(12)

⇒ m∠C = 75°

Consecutive angles of a parallelogram are supplementary

7x+21+5x+15=18012x+36=18012x=144x=12

Step-by-step explanation:

In other words AC = AB

AC = 8x

AB = 2x^2

2x^2 = 8x                 Divide both sides by 2x

2x^2/2x = 8x / 2x    Divide

x = 4

AC = 8x

AC = 8*4

AC = 32

AB = 2x^2

AB = 2 (4)^2

AB = 2*16

The solution to the given system of equations is
(x, y). What is the value of x - y?

Answers

Answer:

20

Step-by-step explanation:

Let's start by rewriting the second equation in terms of "x":

[tex]x+y=5[/tex]

Subtract y from both sides:

[tex]x=5-y[/tex]

Now, substitute "5-y" for "x" in the first equation:

[tex](5-y)^2-y^2=100[/tex]

Note that:

[tex](a-b)^2=a^2-2ab+b^2[/tex]

[tex]25-10y+y^2-y^2=100[/tex]

Cancel out like terms:

[tex]25-10y=100[/tex]

Subtract 25 from both sides:

[tex]-10y=75[/tex]

Divide both sides by -10

[tex]y=\frac{75}{-10}=\frac{15}{-2}=-\frac{15}{2}[/tex]

Now, substitute this value back into either of the equations to solve for x.

[tex]x+y=5\\x-\frac{15}{2}=5\\[/tex]

Add 15/2 to both sides:

[tex]x=5+\frac{15}{2}\\x=\frac{10}{2}+\frac{15}{2}\\x=\frac{25}{2}[/tex]

Now, find the difference:

[tex]x-y=\frac{25}{2}-(-\frac{15}{2})=\frac{25}{2}+\frac{15}{2}=\frac{40}{2}=20[/tex]

A triangle is a polygon with three sides. The sum of angles in a triangle is 180 degrees.

Therefore, let's find the angle of x in the triangle.

Triangle DEF is shown above. Therefore, the equation that can be used to find the value of x can be calculated as follows:

49 + 37 + x = 180

What are the properties of similar triangles?

In Mathematics and Geometry, two (2) triangles are said to be similar when the ratio of their corresponding side lengths are equal and their corresponding angles are congruent.

Additionally, the sum of all of the interior angles of a triangle is always equal to 180 degrees. In this scenario, we can logically deduce that the sum of the given angles are supplementary angles:

m∠1 + m∠2 + m∠3 = 180°

37° + 49° + m∠3 = 180°

86° + m∠3 = 180°

x + 86° = 180° (required equation)
