Answer:

62.5 degrees

Step-by-step explanation:

180-55= 125

125/2 = 62.5

The value for angle [tex]x[/tex] will be [tex]70^0[/tex] .

Angle is when two rays meet together then the space between them is angle.

We have,

[tex]x=?[/tex]

A triangle with one of its angle equals to [tex]55^0[/tex] and two sides are equal .

So,

"When two sides are equal then the interior angles opposite to these lines are also equal".

So,

According to the above mentioned theorem the angle other than the angle [tex]x[/tex] will be [tex]55^0[/tex] .

Now, Using angle sum property,

[tex]x+55^0+55^0=180^0[/tex]

[tex]x=180^0-110^0[/tex]

[tex]x=70^0[/tex]

So, the value of [tex]x[/tex] is [tex]70^0[/tex] which is find out using the angle sum property.

Hence, we can say that the value for angle [tex]x[/tex] will be [tex]70^0[/tex] .

Answer:

47.5

Step-by-step explanation:

47.5=100%

57=120%

The input value is 47.5 when the output is 57.

The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.

Given:

When the output is 120%, the input is 100%.

And the output is 1.2 times the input.

So, we have the output 57.

To find the input number:

Use division process,

The required number = 57 /1.2

The required number = 47.5.

Therefore, the number is 47.5.

Step-by-step explanation:

The question could not be solved because you did not include the image of the prism.

However, from the options; it can be deduced that the prism is a rectangular prism

To calculate the volume of a rectangular prism, you consider the following parameters:

And the Volume is then calculated by the products of the above parameters.

[tex]Volume = Length * Width * Height[/tex]

Take for instance, the attached image:

[tex]Length = 5[/tex]

[tex]Width = 8[/tex]

[tex]Height = 2[/tex]

[tex]Volume = 5 * 8 * 2\ units^3[/tex]

or

[tex]Volume = 80\ units^3[/tex]

Answer:

B I think

Step-by-step explanation:

Answer: Choice B

=========================================================

Explanation:

Let's say we had segment PQ. So the endpoints are P and Q. Let M be the midpoint of segment PQ.

Furthermore, let P have coordinates (x+6, y/3). Dividing by 3 is the same as multiplying by 1/3. So (1/3)y is the same as y/3.

Let Q have the coordinates (r,s). The goal is to express r and s in terms of x and y, as the answer choices indicate.

The midpoint M is located at (2,-5)

---------------------

For now, let's focus on the x coordinates of each point

If we average the x coordinates of P and Q, we'll get the x coordinate of M

So we add up (x+6) and r, then divide by 2, and we should get 2 as a result

( (x coord of P) + (x coord of Q) )/2 = x coord of M

( (x+6) + (r) )/2 = 2

(x+6+r)/2 = 2

Let's solve for r

(x+6+r)/2 = 2

x+6+r = 2*2

x+6+r = 4

r = 4-x-6

r = -2-x

The x coordinate of point Q is -2-x

----------------------

We'll follow the same basic idea for the y coordinates

We then get

( (y coord of P) + (y coord of Q) )/2 = y coord of M

( (y/3) + (s) )/2 = -5

(y/3) + s = -5*2

(y/3) + s = -10

Now solve for s

(y/3) + s = -10

s = -10-(y/3)

This is the y coordinate of point Q.

------------------------------

We found

Point Q is therefore located at (-2-x,  -10-(y/3) )

This points to choice B as the final answer.

Answer:

x= 23 y=88

Step-by-step explanation:

3x+23= 4x

x=23

x and y are supplementary angles so they add up to 180 so then if x is 23

23 x 4= 92

so 180-92 is 88

therefore y is 88 and x is 23
