How do you prove AAS congruence rule?

Step-by-step explanation:

P(-4,7)

Q(-1,-1)

R(-8,-1)

Answer:

3.) x = 4.5

4.) y = 7

Step-by-step explanation:

3 is an easier one than 4. By the triangle midsegment theorem, the midsegment of a triangle will be half of the base if it is parallel to it. AB is our base, so the equation is like this!

[tex]AB = 2(ED)\\9=2(ED)\\4.5=ED[/tex]

Now for 4, it actually is pretty easy. By the same triangle midsegment theorem, we automatically know that EC and EA are congruent, and CD and DB are also congruent. Meaning y equals 7.

But another way we can determine this (the long, kinda unecessary, but useful way) is through examining the relationship that triangles ABC and EDC have!  We know that they are similar triangles by SAS or AA. Meaning, their equation looks something like this...

[tex]4.5(7+y) = 9y\\31.5 + 4.5y = 9y\\31.5=4.5y\\7=y[/tex]

Like I said earlier, 7 is equal to y, but I figured I'd prove it so we are on the same page. Nothing wrong with double-checking ;)

Heart or brainly me!

Given:

Point B has coordinates ​(4,1).

The​ x-coordinate of point A is -4.

The distance between point A and point B is 10 units.

To find:

The possible coordinates of point​ A.

Solution:

Let the y-coordinate of point A be y. Then the two points are A(-4,y) and B(4,1).

Distance formula:

[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

The distance between point A and point B is 10 units.

[tex]\sqrt{(4-(-4))^2+(1-y)^2}=10[/tex]

Taking square on both sides, we get

[tex](8)^2+(1-y)^2=100[/tex]

[tex](1-y)^2=100-64[/tex]

[tex](1-y)^2=36[/tex]

Taking square root on both sides, we get

[tex](1-y)=\pm \sqrt{36}[/tex]

[tex]-y=\pm 6-1[/tex]

[tex]y=1\mp 6[/tex]

[tex]y=1-6[/tex] and [tex]y=1+6[/tex]

[tex]y=-5[/tex] and [tex]y=7[/tex]

Therefore, the possible coordinates of point​ A are either (-4,-5) or (-4,7).

Answer:

x^(2.5) ("x to the power 5/2")

Step-by-step explanation:

(x^2)(√x) can also be written as x·x·x^(1/2).  We just add the exponents together:  (x^2)(√x) =  x^1·x^1·x^(1/2) = x^(2.5) ("x to the power 5/2").

See Explanation

Step-by-step explanation:

Given

The given proportion can be represented as:

[tex]1\ bag = 4yd^2[/tex]

Required

The additional number of mulch needed

The question has incomplete details, as the amount of mulch he has applied and the area of the flower garden are not given.

So, I will make some assumptions to solve this question.

Let the area of his flower garden be x.

So, we have:

[tex]1\ bag = 4yd^2[/tex]

[tex]y = x\ yd^2[/tex]

Cross multiply

[tex]4yd^2 * y = xyd^2 * 1\ bag[/tex]

Make y the subject

[tex]y = \frac{x\ yd^2 * 1\ bag}{4yd^2}[/tex]

[tex]y = \frac{x* 1\ bag}{4}[/tex]

[tex]y = \frac{x}{4}\ bag[/tex] --- This represents the total amount of mulch required for the flower garden

--------------------------------------------------------------------------------------------------------

Assumptions

Assume that [tex]x = 16[/tex],

So, we have:

[tex]y = \frac{x}{4}\ bag[/tex]

[tex]y = \frac{16}{4}[/tex]

[tex]y = 4[/tex]

i.e 4 bags are needed.

Assume he has applied 2 bags already.

The number of bags needed to apply will be:

[tex]y - 2[/tex]

[tex]y - 2 = 4 - 2[/tex]

[tex]y - 2 = 2[/tex]

2 more bags needed

Step-by-step explanation:

The slope of the line is going down 1/2 at a time

This question requires the understanding of trigonometric identities. I'll list the ones that are needed to answer this question:

cotθ = 1 / tanθ

tanθ = sinθ / cosθ

Look at the latter identity. We can rewrite it as such:

tanθ * cosθ = sinθ

We are given the expression:

cosθ * tan²θ * cotθ

Referring to the first trigonometric identity above, substitute cotθ:

cosθ * tan²θ * (1 / tanθ)

Multiply tan²θ and the fraction:

cosθ * (tan²θ / tanθ)

cosθ * tanθ

Refer to the second trigonometric identity:

cosθ * tanθ

sinθ

cosθ * tan²θ * cotθ = sinθ

Answer:

x=2/3,-3,x=0.6 repeating decimals,-3

Step-by-step explanation:

Answer:

10.29 (rounded = 10.30)

Step-by-step explanation:

X = a^2 + b^2 = c^2

X = 9^2 + 5^2 = c^2

X = (81) + (25) = c^2

X = 106 = c^2

X = √106 = c^2

X = 10.295630141 = c^2

X = 10.03 = c^2 (10.03 is 10.295630141 rounded to the nearest tenth)
