Is triangle ABC similar to triangle DEF? Why or why not?
Answer:
No, because not all corresponding angles are congruent.
Step-by-step explanation:
In order for two triangles to be similar you must have that you know at least 2 corresponding angles are congruent which would also imply the third set of angles are also congruent. You can also tell if two triangles are similar based on their corresponding sides being proportional. Without even checking the proportionally part of corresponding sides, I see the 3 angles in the first triangle do not have the same measurement as the one in the second triangle. Therefore, the triangles cannot possibly by similar.

Answer:
by BPT it will be solved
Step-by-step explanation:
CQ/QA=CP/PD
x+2/x=5x+4/3x
by cross multiplication
answer will be 1
Parallel sides are sides that are equidistant from one another. The value of x is 1
Given that:
[tex]CQ = x + 2\\QA = x\\CP = 5x + 4\\PD = 3x[/tex]
Since:
QR & AB are parallel, and RP & BD are parallel.
Then by theorem of similarities:
[tex]\frac{CQ}{QA} = \frac{CP}{PD}[/tex]
This gives:
[tex]\frac{x+2}{x} = \frac{5x + 4}{3x}[/tex]
Multiply both sides by 3x
[tex]3x \times \frac{x+2}{x} = \frac{5x + 4}{3x} \times 3x[/tex]
[tex]3 \times (x+2) = 5x + 4[/tex]
Open bracket
[tex]3x+6 = 5x + 4[/tex]
Collect like terms
[tex]5x - 3x = 6 -4[/tex]
[tex]2x = 2[/tex]
Divide both sides by 2
[tex]x = 1[/tex]

Quadrilateral WXYZ is a square. If WT=6, find each measure?
We know that the diagonals of a square bisect each other which results in the formation of 4 - 90° angles . Which means ZX = 2 × WT . Then ,
= ZX = 2 × 6
= ZX = 12 ( ZX is a diagonal )
Side XY =
XY = √2 d/2
XY = √2 . 12/2
XY = 8.48528
m∠WTZ = 90° ( as the diagonals of a square intersect to form a complete angle ( 360° ) which is divided into four equal parts , each part being 90° )
m∠WTZ = 90°
m∠WYX = 45° ( WYX is half of one of the interior angles in this square which will mean it will be equal to 45° )
Therefore , m∠WYX = 45°
In short :ZX = 12
XY = 8.48528
m∠WTZ = 90°
m∠WYX = 45°

2. The floor plan for a rectangular building states that the length of the building is to be 8 meters more than 3 times its width . If the floor area is to be 256 square meters, what must be the length and width of the building?
Area of a rectangle = Length × Width
Length of the building is to be 8 meters more than times its width.
= Length = 3W + 8
Area = 256m²
Hence:
256 =( 3W + 8 )× W
256 = 3W² + 8W
= 3W² + 8W - 256
Factorise
= 3W(W - 8) + 32(W - 8)
= (3W + 32) ( W - 8)
W - 8 = 0
W = Width = 8m
Length = 3W + 8
Length = 3(8) + 8
= 24 + 8
= 32m.
D. 32 meters long and 8 meters wide
3. The area of the dining room is 130 square units. If the width is 3 meter less than its length what is the width
of the room?
A. 10 units
B. 11 units
C 12 units
D. 13 units
Area = Length × Width
The width is 3 meter less than its length
W = L - 3
Area = 130 square units
Hence:
130 = L (L - 3)
130 = L² - 3L
L² - 3L - 130
= L² + 10L - 13L - 130
= L(L + 10) - 13(L + 10)
= (L - 13) (L + 10)
L - 13 = 0
L = Length = 13 units
L + 10 = 0
L = -10 units.
W = L - 3
L = 13 units
W = 13 - 3
W = 10 units
Therefore, the width of the room is 10 units
A. 10 units
4. One of the factors of 2b² + 15b-50 is b + 10. What is the other factor?
A.2b - 10
B. 2b -5
C. 2b +5
D. 2b + 10
2b² + 15b -50
One of the factors is b +10.
We factorise
2b² + 15b - 50
= 2b² + 20b - 5b - 50
= 2b(b + 10) - 5(b + 10)
= (2b - 5) (b + 10)
The other factor is 2b - 5
B. 2b -5

h = 2(15x² - 10x)/5x
h = 30x² - 20x/5x
h = 30x²/5x - 20x/5x
= 6x - 4 cm

5x - 3(x + 9) + 10 = 4
Answer:
[tex]x = \frac{21}{2}[/tex]
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
5x − 3(x+9) + 10 = 4
5x + (−3)(x) + (−3)(9) + 10 = 4 (Distribute)
5x + −3x + −27 + 10 = 4
(5x+−3x) + (−27+10) = 4 (Combine Like Terms)
2x + −17 = 4
2x − 17 = 4
Step 2: Add 17 to both sides.
2x − 17 + 17 = 4 + 17
2x = 21
Step 3: Divide both sides by 2.
[tex]\frac{2x}{2} = \frac{21}{2}[/tex]
[tex]x =\frac{21}{2}[/tex]

D is between C and E. CE = 6x, CD = 4x + 8, and DE = 28. Find CE.
Please Answer ASAP!!!
(BTW it's high school geometry)
Answer:
CE=108
Step-by-step explanation:
*I don't have my phone with me so I can't add a picture of what I drew*
First, draw a line. On one end, write C. On the other end, write E. In the middle of them, write D. The question states that CE=6x, so on the bottom of the line, write 6x. On top on the first half write 4x+8 (between C and D). On the other half between D and E write 28.
According the the information we have been given and the diagram we made, CD+DE=CE. Hence, (4x+8)+28=6x
(4x+8)+28=6x (subtract four from both sides)
8+28=6x-4x (combine like terms)
36=2x (divide two from both sides)
x=18
Now, substitute 18 for x in 6x (CE=6x)
CE=6(18)
CE=108

6=1/12v solve each equation. Check your solution
Answer:
112v=6 1 12 v = 6 . 12
Step-by-step explanation:
The solution to the equation is v = 72.
We have,
To solve the equation 6 = (1/12)v, we can follow these steps:
Multiply both sides of the equation by 12 to eliminate the fraction:
6 * 12 = (1/12)v * 12,
72 = v.
Therefore, the solution to the equation 6 = (1/12)v is v = 72.
To check this solution, we substitute v = 72 back into the original equation:
6 = (1/12)(72),
6 = 6.
Since both sides of the equation are equal, we can confirm that the solution v = 72 is correct.
Thus,
The solution to the equation is v = 72.
