The two triangles are similar. There are two possible values of x. Work out each of these values. State both assumptions you make in your working. You must state which two triangles you are assuming to be similar.
Answer:
ΔABE ~ ΔACD, x = 2ΔABE ~ ΔADC, x = 17Step-by-step explanation:
ΔABE ~ ΔACD
AC/AB = AD/AE
(10+x)/10 = (15+3)/15
1 +x/10 = 1 +0.2 . . . expand each ratio
x = 10(0.2) . . . . . . . subtract 1 and multiply by 10
x = 2
__
ΔABE ~ ΔADC
AC/AE = AD/AB
(10+x)/15 = (15+3)/10
10 +x = 27 . . . . . . . . multiply by 15
x = 17 . . . . . . . . . . . . subtract 10

Additional comment
The triangles can be declared similar in 6 ways, but it does no good to match a marked side with an unmarked side. Hence, only two of the possible similarity statements will result in a solution for x.
Answer:
This will give you 5/5
x = 17

Assuming triangle ABE is similar to ACD
Assuming traingle ABE is similar to ADC
Step-by-step explanation:
18/10 = 1.8 (S.F)
15 x 1.8 = 27
27-10 = 17
x = 17
15+3=18
18/15= 1.2 (S.F)

Does anyone know the answer?
Answer:
1=163 degrees
2=×=10 degrees
3=×=3
Step-by-step explanation:
54x+1+9x-10=180 we are using this expression because alternate angles add up to 180 degrees
54x+9x+1-10=180
63x-9=180
63×=180+9
63×=189
63×÷63×=189÷63×
X=3
Angle in bold print is (54x+1)
54×3=162
162+1=163 degrees
No.2 Find x
7x+35+x+65 =180
7x+x+35×65=180
8x+100=180
8x=180-100
8x=80
8x÷8x=80÷8
X=10 degrees
No.3 Find x
54x+1+9x-10=180
54x+9x+1-10=180
63x-9=180
63x=180+9
63x=189
63x÷63x=189÷63

How to identify the parent function given an equation ?
Answer:
You can identify the parent function by making the equation into its simplest form.
Step-by-step explanation:
Remove all transformations from the equation (such as plus/minus signs, constants, and extra terms in the equation).
ex. y= -3x^2+15
The parent function would be y=x^2 after removing everything.
Hope this helps! :)

Find the midpoint of the line segment joining the points (-1, -2) and (-3, 13).
The midpoint is
(Simplify your answer. Type an ordered pair)
A mid-point divides a line segment into 2 equal parts . Hence the line is divided in 1 : 1 ratio.
Let
x(1) = -1
y(1) = -2
x(2) = -3
y(2) = 13
So according to Section formula , cordinate of the mid - point (x' , y') =
[tex](x' , y') = ( \frac{ {x}^{1} + {x}^{2} }{2} , \frac{{y}^{1} + {y}^{2} }{2} )[/tex]
So using the formula & putting the values above
[tex]( \frac{ - 1 - 3}{2} , \frac{ - 2 + 13}{2} )[/tex]
[tex] = > ( \frac{ - 4}{2} , \frac{11}{2} )[/tex]
[tex] = > ( - 2 , 5.5)[/tex]
So the mid - point is (-2 , 5.5)

what is the perimeter of a rectangle with a length of (x^2+x) and a width of (2x^2+3x)
Answer:
Perimeter = 6x² + 8x
Step-by-step explanation:
Perimeter = 2(length + width)
perimeter = 2((x²+x)+(2x²+3x))
perimeter = 2(x²+2x² + x+3x)
perimeter = 2(3x² + 4x)
perimeter = 2*3x² + 2*4x
perimeter = 6x² + 8x
The length of a rctangle is to more than the
width. The perimeter of the rectangle is 72 meters
What is the length of the rectangle?
Answer:
19 m
Step-by-step explanation:
The width is 2 less than the length, so the perimeter is ...
P = 2(L +W)
72 = 2(L +(L -2))
76 = 4L . . . . . . . . add 4
19 = L
The length of the rectangle is 19 meters.

i need the answer in a fraction. THANXS!
w−2+2w=6+5w please helppp
The solution to the equation W - 2 + 2w = 6 + 5w is W = -4.
To solve the equation W - 2 + 2w = 6 + 5w, follow these steps:
Begin by gathering the terms with W on one side and the terms without W on the other side of the equation.
Start by subtracting 2w from both sides:
W - 2 + 2w - 2w = 6 + 5w - 2w
Simplify:
W - 2 = 6 + 3w
Next, move the constant term (6) to the left side by subtracting 6 from both sides:
W - 2 - 6 = 6 + 3w - 6
Simplify:
W - 8 = 3w
Now, let's isolate the variable W by subtracting 3w from both sides:
W - 3w - 8 = 3w - 3w
Simplify:
-2w - 8 = 0
Finally, solve for W by adding 8 to both sides:
-2w - 8 + 8 = 0 + 8
Simplify:
-2w = 8
Divide both sides by -2 to isolate w:
(-2w) / -2 = 8 / -2
Simplify:
w = -4

Certain cooking oil has a density of 0.91 grams per milliliter. Which of the following series of calculations correctly determines the mass, in kilograms, of 15 liters of this oil?
Answer:
Step-by-step explanation:
Here is a picture of the answer, since I couldn't put into words!
The mass of 15 liters of oil is 13.65 kg.
What are Arithmetic operations?Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.
The operator that performs the arithmetic operations are called arithmetic operators.
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
/ Division operation: Divides left-hand operand by right-hand operand
For example 4/2 = 2
What is the density?Density is the ratio of the mass of the body to the volume of the body.
Density = Mass / Volume
Given that oil has a density of 0.91 grams per milliliter
To determines the mass, in kilograms, of 15 liters of this oil
Rearranging the equation,
Mass = Density × Volume
∵ 15 liters = 15000 milliliters (ml)
So, 0.91g/ml x 15000ml = 13650g
∵ 1 kilogram = 1000grams
⇒ 13650g / 1000g/kg
⇒ 13.65kg
Thus, the mass of 15 liters of oil is 13.65kg.
