How do you prove AAS congruence rule?
Answers
The two triangles are congruent if two angles and a non-included side of one triangle are congruent with two angles and the corresponding non-included side of a second triangle. So it was proved.
The two triangles are congruent if two angles and a non-included side of one triangle are congruent with two angles and the corresponding non-included side of a second triangle.
If angle ad, side ac-df, and angle cf are present, then ABCDEF is true.
To support: By the angle sum property, ABC DEF A+B+C=180° ______ (1)
In DEF D+E+F=180°___________ (2) (By angle sum property)
From (1) and (2), A+B+C= D+E+F A+E+F= D+E+F
(Given B=E and C=F) A=D ____________________ (3)
Currently, in ABC and DEF A=D (from (3))
AC = DF (Given)
C=F (Give (AAS congruency)
So it was proved.

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. What are the possible coordinates of point A?
Answers
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).

Simplify the following trigonometric expression. cosθtan²θcotθ
Answers
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

If DE is the midsegment of ABC what is the value of x AND y?
Answers
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 ;)

James has a sidewalk that runs through his flower garden. He needs to put more mulch in the flower garden. If one bag of mulch covers 4 square yards, how many bags of mulch will he need?
Answers
Answer:
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
