Answer:
Step-by-step explanation:
∠A + ∠B + ∠C = 180 {Angle sum property of triangle}
∠A + 65 + 55 = 180
∠A + 120 = 180
∠A = 180 - 120
∠A = 60
If two triangles are similar, then the corresponding angles of two triangles are congruent.
z = ∠A
z = 60
In ∆ ABC,
[tex]\angle[/tex] A + [tex]\angle[/tex] B + [tex]\angle[/tex] C = 180° .... (Angle sum property of a triangle)
Here, we have:
[tex]\angle[/tex] B = 65°[tex]\angle[/tex] C = 55°Substituting values,
[tex]\dashrightarrow\sf{\angle A + 65 + 55 = 180} \\ \\ \dashrightarrow\sf{\angle A + 120 = 180} \\ \\ \dashrightarrow\sf{\angle A = 180 - 120} \\ \\ \dashrightarrow{\boxed{\sf{\gray \angle A = 60 \: \bigstar}}}[/tex]As we know that,

How to determine the length of V'B'From the question, we have the following parameters that can be used in our computation:
The triangle and the image
Also, we know that the triangles are reflected
The reflection transformation is a rigid transformation
This means that
V'B' = VB
From the figures, we have

Solve the equation and enter the value of x.
11x + (-4x) = 56
X = ?
Answer:
[tex] \sf \: x = 8[/tex]
Step-by-step explanation:
Given equation,
→ 11x + (-4x) = 56
Now the value of x will be,
→ 11x + (-4x) = 56
→ 11x - 4x = 56
→ 7x = 56
→ x = 56/7
→ [ x = 8 ]
Hence, the value of x is 8.

into the jar shown. About how much jelly will he
need to fill the jar to 0.5 inch from the top? Circle
the correct answer. (Use 3.14 for T, and round to the
nearest whole.)
Answer:b
Step-by-step explanation:
Option B will be the correct option.
Given in the question,
Radius of the cylindrical jar = 2 inchesHeight of the jar = 5 in.Height of the jelly in the jar = (5 - 0.5) = 4.5 inchesExpression for the volume of a cylinder = [tex]\pi r^{2}h[/tex]

Find the slope of the line that passes through (4,-2) and (2,4) please
Answer: -3
Step-by-step explanation:
To find the slope of a line we need two coordinates on the line. Any two coordinates will suffice. We are basically measuring the amount of change of the y-coordinate, often known as the rise, divided by the change of the x-coordinate, known the the run. The calculations in finding the slope are simple and involves nothing more than basic subtraction and division.

Now to find <x, we can use the exterior angles theorem a couple of times.
<x=<p+<AGE
<x=30 degrees + <AGE
Now use the theorem again to find <AGE
<AGE=<q+<BIG
Now use substitution for <q and for <AGE
<x=30 degrees+60 degrees+ <BIG
We put this to the side for now and try solve for <CHD which is not very difficult
<CHD=180-45-20=115
We can also clearly figure out <HFI using vertical angles theorem.
<HFI=<Y
Because they all form a triangle we can conclude that <y+<BIG=180 degrees-<FHI= 180-115=65 degrees
substitution again
<x+<y=30+60+<BIG+<HFI (remember <HFI = <y vertical angles theorem)
<x+<y=30+60+65 (remember how we did before these 2 angles adds up to 65?)
<x+<y=155 degrees
Now please don't hate me on this, I'm sure there is more efficient ways to explain this problem, this is just my way from trial and error.
Tip for next time you are stuck on a geometry problem, don't be afraid to draw the graph again on paper and add lines to it!

Roxana tiene que responder la siguiente consigna que le dio la seño ``si para dividir un numero por 10 le debo suprimir a ese numero la ultima sifra como por ejemplo 120÷10 =12 0 122÷10 =12 y me sobran 2 ¿como harias para dividir un numero decimal como 0,1 en 10 ?
Answer:
Para dividir un número decimal como 0.1 en 10 se debe adicionar un 0 del lado derecho del punto, es decir, del lado de los decimales.
Step-by-step explanation:
Dado que, si para dividir un número por 10 le debo suprimir a ese número la última cifra, como por ejemplo 120/10 es igual a 12, o 122/10 es igual 12 y me sobran 2, para dividir un número decimal como 0.1 en 10 se debe adicionar un 0 del lado derecho del punto, es decir, del lado de los decimales. Esto se comprueba al realizar dicha división:
0.1 / 10 = 0.01
0.01 / 10 = 0.001

Travis plays a trivia game. He earns 2 points for each correct answer and loose 0.5 points for each incorrect answer. He get 13 correct answer. He gets 13 correct answer and 2 incorrect answer
Answer:
If you are asking for how many points he has now that would be 25 points
Step-by-step explanation:
Because he earns 2 points for each correct we can do 13x2=26
Because he loses 0.5 points for every wrong answer we can do 0.5x2=1
So, with that information we can do 26-1=25

Write an equation of a line that passes through the point (-2, 4) and has a
slope of 5.
Answer:
y = 5x + 14
Step-by-step explanation:
An equation consists of y = mx + b. The m is the slope, which we already know is 5.
To find the y-intercept, plug the coordinates into the equation so far, which is y = 5x + b.
y = 5x + b
4 = 5(-2) + b
4 = -10 + b
14 = b
So the equations is y = 5x + 14.

Answer:
x = 3√2 , y = 6
Step-by-step explanation:
In given triangle,
3√2 = x
and y is hypotenuse.
Using Pythagoras theorem
hypotenuse = √Perpendicular² + Base²
hypotenuse = √(3√2)² + (3√2)²
hypotenuse = √18 + 18
hypotenuse = √36
hypotenuse = 6
So,
x = 3√2 , y = 6

In an ice cream shop there is some money in a drawer. After 6 ice creams were sold, there were 70 euros left in the drawer. After a total of 16 ice creams were sold, there were 120 euros left in the drawer. How many euros were there in the drawer at the start?
Answer: There were 40 euros in the drawer at the beginning.
Step-by-step explanation:
When we subtract 6 from 16, we get 10 more ice-creams were sold.
Similarly, we subtract 70 from 120, we get 50 euros was the total selling price of 10 ice-creams.
i.e. Selling price of 1 ice-cream = (50)÷10 =5 euros
Selling price of 6 ice-creams = 6 x 5 = 30 euros
Money in the drawer at the beginning = 70-30 = 40 euros
Hence, there were 40 euros in the drawer at the beginning.
