Given CAD is a right angle and AB is bisecting CAD and if DAB=(7x-4) find X
Answer:
7°
Step-by-step explanation:
Just a quick clarification, swap A and B on the diagram.
If CAD is a right angle, it is equal to 90°. Since AB is bisecting CAD, angles CAB and DAB are congruent(equal) and complementary(add up to 90) angles, and thus equal 45°. By the transitive property, if DAB = (7x - 4)° and also equals 45°, (7x - 4)° = 45°. So we can simply solve for x.
7x - 4 = 45
7x - 4 + 4 = 45 + 4
7x = 49
7x/7 = 49/7
x = 7
Shayna enlarged a square photo by adding 10 inches to each side so it could be seen on a large poster. The area of the enlarged photo is 256 square inches. In the equation (x + 10)2 = 256, x represents the side measure of the original square photo.
What were the dimensions of the original photo?
pls hurry
4 inches by 4 inches
6 inches by 6 inches
10 inches by 10 inches
12 inches by 12 inches
Answer:
The correct answer is:
6 inches by 6 inches
Step-by-step explanation:
Given that
Area of Enlarged photo = 256 square inches
Let x be the side of original photo
then the equation for area of new enlarged photo will be:
[tex](x+10)^2 = 256[/tex]
We have to solve the given equation to find the side length of original photo
Taking square root on both sides
[tex]\sqrt{(x+10)^2} = \sqrt{256}\\x+10 = 16[/tex]
Subtracting 10 from both sides
[tex]x+10-10 = 16-10\\x = 6[/tex]
So the side length of original photo is 6 inches. The dimensions will be 6 inches by 6 inches.
Hence,
The correct answer is:
6 inches by 6 inches

5. Dion created a scale drawing of the school library in his art class. In the scale drawing, the length of the library is 13
inches. The length of the actual library is 78 feet.
Which scale did Leon use to create the scale drawing of the school library?
A. 1 inches represents 6 feet
B. 1 inches represents 1/6 foot
C. 6 inches represents 1 foot
D. 6 inches represents 1/6 foot
So the scale used was
1 inch = 6 feet ANSWER = AStep-by-step explanation:
Given;
Length of library on drawing = 13 inches
Actual length of library = 78 feet
In order to find the scale we divide the actual length by the length of library on drawing.
So, scale = 1 inch = 6 feet
Keywords: Scale, Maps
Answer:
C
Step-by-step explanation:

Please answer this question. The answer is 2.77cm but my teacher wants a two triangle solution.
9514 1404 393
Answer:
5.69 cm
Step-by-step explanation:
The mnemonic SOH CAH TOA can remind you of the relationships between angles and sides in a right triangle. Here, the useful ones are ...
Cos = Adjacent/Hypotenuse
Sin = Opposite/Hypotenuse
__
Using the first of these, we can find GD:
cos(52°) = GC/GD
GD = GC/cos(52°)
Using the second of these, we can find GH:
sin(64°) = GH/GD
GH = GD·sin(64°)
Substituting for GD, we find ...
GH = GC·sin(64°)/cos(52°)
GH ≈ (3.9 cm)(0.8988/0.6157)
GH ≈ 5.69 cm
_____
Additional comment
The length 2.77 cm given in your question is the approximate length of DH. That solution is DH = (3.9 cm)·cos(64°)/cos(52°) ≈ 2.7769 cm ≈ 2.78 cm.

Answer:
16.7
Step-by-step explanation:
We can use the Pythagorean Theorem [tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex]. So we write the equation below and solve for b.
[tex]9^{2}[/tex] + [tex]b^{2}[/tex] = [tex]19^{2}[/tex]
81 + [tex]b^{2}[/tex] = 361
[tex]b^{2}[/tex] = 280
b = 16.7
Answer:
h²=p²+b²
(19)²-(9)²=b²
361-81= b²
b²=280
b= √280
:. b=+-16.733

Use the equation y = x - 2 and perform a reflection over the x-axis. Write an equation in 2
1
slope intercept form that represents the new line.
Answer:
So after reflecting over the x-axis, the equation is:
[tex]-y = x-2[/tex]
so the equation in the slope-intercept form
[tex]-y = x-2[/tex]
[tex]y=-x+2[/tex]
Here,
The slope = m = -1The y-intercept = b = 2Step-by-step explanation:
Given the equation
[tex]y = x - 2[/tex]
Reflecting over the x-axis inverts the sign of the y-coordinate, but the sign of the x-coordinate remains the same.
So after reflecting over the x-axis, the equation is:
[tex]-y = x-2[/tex]
Now, writing the equation in the slope-intercept form
[tex]y=mx+b[/tex]
where m is the slope and b is the y-intercept
so the equation in the slope-intercept form
[tex]-y = x-2[/tex]
[tex]y=-x+2[/tex]
Here,
The slope = m = -1The y-intercept = b = 2Hey, Whats The answer please explain your answer marking brainliest:D....................................
Answer:
I think it's answer choice A!
Step-by-step explanation:
The reason why I think that it is A is because of the given y values. The x values are consistent through all of the given choices, but if graphed, there is a distance of three units between the y-value of 4 and the y-value of 7. I personally like to use Desmos when it comes to trying to get a visual graph of coordinates. I hope this at least helped a little!
The distance between (2,4) and (2,7) is 3 therefore, these two points have a distance of 3 units, therefore, option (A) will be correct.
How to find the distance between two points?Let's consider we have two points (x₁, y₁) and (x₂, y₂) the distance between these two points is given by the formula;
[tex]d = \sqrt {\left( {x_1 - x_2 } \right)^2 + \left( {y_1 - y_2 } \right)^2 }[/tex]
The distance between with two points (x₁, y₁) and (x₂, y₂) is given as,
[tex]d = \sqrt {\left( {x_1 - x_2 } \right)^2 + \left( {y_1 - y_2 } \right)^2 }[/tex]
In option (A),
Points are (2,4) and (2,7).
The distance between them will be,
[tex]d = \sqrt {\left( {2 - 2 } \right)^2 + \left( {4 - 7 } \right)^2 }[/tex]
d = √(3²) = 3
Hence "The distance between (2,4) and (2,7) is 3 therefore, these two points have a distance of 3 units".

triangle FGH with vertices F(-7,8) G(-1,1) and H(-8,4): 270 counterclockwise
The image of the triangle when rotated is F' = (8, 7), G' = (1, 1) and H' = (4, 8)
How to determine the image of the triangle when rotated?The vertices of the triangle are given as:
F = (-7,8)
G = (-1,1)
H = (-8,4)
The transformation rule is given as
270 degrees counterclockwise rotation
The rule of 270 degrees counterclockwise rotation is
(x,y) = (y,-x)
When the above rule is applied to the vertices of the triangle, we have:
F' = (8, 7)
G' = (1, 1)
H' = (4, 8)
Hence, the image of the triangle when rotated is F' = (8, 7), G' = (1, 1) and H' = (4, 8)
