Answer:
AB = 15
BD = 5
Step-by-step explanation:
Statement__________________| Reason______________
1) m<1 = m<2, AB = AC | Given
2) AD = AD | Reflexive property
3) ΔABD = ΔADC | Side - angle - side
4) AB = AC = 15 | Corresponding part of congruent triangles . | are congruent
5) BD = DC = 5 | Corresponding parts of congruent triangles . | are congruent
Answer:
BD = 5, AB = 15Step-by-step explanation:
AB = AC and AC = 15 (both given)
⇒ AB = 15AB≅AC, ∠1≅∠2, AD≅AD (first two given and the last one is the common side)
⇒ ΔABD ≅ ΔACD by SASBD≅DC as corresponding sides
BD = DC and DC = 15
⇒ BD = 5Related Questions

If f(x) = 11 - 6(x - 8), what is f(-3)?
Answers
Answer:
We conclude that:
[tex]f\left(-3\right)=77[/tex]Step-by-step explanation:
Given the function
[tex]f(x) = 11 - 6(x - 8)[/tex]
Important Tip:
In order to determine f(-3), all we need is to substitute x = -3 in the function equationsubstitute x = -3 in the equation
[tex]f(x) = 11 - 6(x - 8)[/tex]
[tex]f(-3) = 11 - 6(-3 - 8)[/tex]
[tex]f\left(-3\right)\:=\:11-\left(-66\right)[/tex]
[tex]f\left(-3\right)\:=\:11+66[/tex] ∵ Apply rule -(-a) = a
[tex]f\left(-3\right)=77[/tex]
Therefore, we conclude that:

About 35% of all U.S. households have a cellular phone. If you called 7 households to inquire if they have a cell phone.
To calculate this distribution, what would you set p equal to? p =
What would q be equal to? q =
What would n be equal to? n =
Answers
Answer:
p = 0.35
q = 0.65
n = 7
Step-by-step explanation:
To calculate the distribution, we have the following values;
p = 35% = 35/100 = 0.35
q = 1-p = 1-0.35 = 0.65
n = 7
Answer:
p = 0.35
q = 0.65
n = 7

Side length = [tex]2\sqrt{3}[/tex] in
Step-by-step explanation:
Area of the given hexagon = 6 × (Area of the triangular section)
Area of the triangular section = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]
= [tex]\frac{1}{2}(2)(\sqrt{3})^{\frac{x}{12}}(\sqrt{3})^{\frac{x}{6}}[/tex]
= [tex](\sqrt{3})^{\frac{x}{12}}[(\sqrt{3})^2]^{\frac{x}{12}}[/tex]
= [tex](\sqrt{3})^{\frac{x}{12}}(3)^{\frac{x}{12}}[/tex]
= [tex](3\sqrt{3})^{\frac{x}{12}}[/tex]
Now area of the given hexagon = [tex]6(3\sqrt{3})^{\frac{x}{12}}[/tex]
Since, area of the hexagon is = [tex]18\sqrt{3}[/tex] in²
[tex]6(3\sqrt{3})^{\frac{x}{12}}=18\sqrt{3}[/tex]
[tex](3\sqrt{3})^{\frac{x}{12}}=(3\sqrt{3})^1[/tex]
[tex]\frac{x}{12}=1[/tex]
x = 12
Therefore, side length = [tex]2(\sqrt{3})^{\frac{x}{12}}[/tex]
= [tex](2\sqrt{3})^{\frac{12}{12}}[/tex]
= [tex]2\sqrt{3}[/tex] in.

What is the solution
-3x + y = 2
y = x + 4
Answers
Answer:
to find the solution, we substitute y = x + 4 into the other equation.
-3x + (x + 4) = 2
-3x + x + 4 = 2
-2x = 2 - 4
-2x = -2
x = 1
to find y, we substitute x to the x variable in the y equation.
y = 1 + 4
y = 5
therefore, when combined, it is (1,5).
5x + 3y = 6
-3x - 3y = 6
Answers
Answer:
(x,y)=(6,-8)
x=6, y=-8
Step-by-step explanation:
There are many was to answer this question, some are substitution and elimination. I am going to use the substitution method.
Your system of equation is 5x+3y=6 and -3x-3y=6
5x+3y=6
-5x -5x
3y=6-5x
Now you substittion the first equation to the sencond one. It will look like:
-3x-(6-5x)=6
-3x-6+5x=6
2x-6=6
+6 +6
2x=12
Divide both sides by 2 and you get
x=6
Now lets substiton x inot the orgianl equation.
-3(6)-3y=6
-18-3y=6
+18 +18
-3y=24
Divide both sides by -3
y=-8
So, the answer is x=6, y=-8

Brainliest to whoever answers first!!!Z'(5, -7) is the image of Z after a reflection
in the line y=x. What are the coordinates
of Z?
Answers
Answer:
I think its Z (-5, 7)
Step-by-step explanation:
Here :)
The coordinates of Z is (7, -5).
Given that, Z'(5, -7) is the image of Z after a reflection in the line y=x.
We need to find the coordinates of Z.
What is the reflection in the line y=x?When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x). the line y = -x is the point (-y, -x).
So, the coordinates of Z become (7, -5).
Therefore, the coordinates of Z is (7, -5).

Hi! When I type into the calculator and multiply 0.12 and 100 it comes out as 13.2, why is that?
Answers
Answer:
because it is a decimal so it multiplies 100 by the decimal which is a smaller number, almost like how when you divide it becomes a smaller number.
Step-by-step explanation:
hope this helps:)
i'm not sure why that is, but the only thing i can assume is that either your calculator is broken somehow or you are accidentally typing in the wrong numbers.
you might also have forgotten to clear your calculator before attempting to put in 0.12 x 100.
i recommend using an online calculator for the time being if your calculator is faulty/having issues.
someone help I don't know this trig question
Answers
Answer:
Bill is 9.80 km apart from Concert
Step-by-step explanation:
It's given in the question,
m∠B = 75°
m∠C = 45°
By triangle sum theorem,
m∠A + m∠B + m∠C = 180°
m∠A + 75° + 45° = 180°
m∠A = 180° - 120°
m∠A = 60°
By sine rule,
[tex]\frac{\text{sin}(\angle A)}{BC}=\frac{\text{sin}(\angle C)}{AB}[/tex]
[tex]\frac{\text{sin}(60)}{BC}=\frac{\text{sin}(45)}{8}[/tex]
BC = [tex]\frac{8\text{sin}(60)}{\text{sin}(45)}[/tex]
= 9.80 km
Therefore, Bill is 9.80 km apart from Concert.

What is XY? .........................
Answers
Answer: B i guess
Step-by-step explanation:
The hypotenuse side XY of given right angle at Z is [tex]5\sqrt{2}[/tex].
Given that in triangle XYZ :
∠X=45°
∠Y=45°
XY=5
And right angled at Z, that is, ∠Z=90°.
Since, ∠X=∠Y=45°
Therefore, XZ=YZ=5
Now,
[tex]\sin \theta = \dfrac{hypotenuse}{opposite}[/tex].
Here, θ=45°.
Therefore,
[tex]\sin \theta=\dfrac{5}{XY}\\\\\sin 45\°^=\dfrac{5}{XY}\\\dfrac{1}{\sqrt{2} } =\dfrac{5}{XY}\\\\XY=5\sqrt{2}[/tex]
Thus, the side XY=[tex]5\sqrt{2}[/tex].
