In Figure 1 :- In figure 1 , we have given everything we don't need to determine anything in figure 1 In Figure 2 :- Here, we have to determine the measure of sides ,braces and angles with least number of known measures,Let's start ,
From the figure, we can assume the beam forms as AD, BC, EF , GH and so on.
Therefore,
[tex]\sf{ ABCD , AEFD, AGHD.. so \:on similar\: to \:each \:other }[/tex]
So,
[tex]\sf{ Angle\:BAD = Angle\:EBC = Angle\:GEF}[/tex]
Or,
[tex]\sf{ Angle\: ADC = Angle\:BCF = Angle\: EFH }[/tex]
Now, By using similarity theorem we can determine their sizes, braces and angles that is,
[tex]\sf{\red{ AD/BC = AB/AE = CD/CF = BC/EF}}[/tex]
[tex]\bold{\huge{\blue{\underline{Answers :- }}}}[/tex]
Answer 1 :-
For answering the above questions we use knowledge and practices regarding the questions we can do the activity by making figures of unknown sides by assuming it in the form of x, y.so that we can find the known values.
Answer 2 :-
The best way of solving the above questions is that it is already given in the question that the beam is symmetrical so, here we can use similarity theorem.
Answer 3 :-
It necessary to learn about trapezoid and it's properties because if we don't know the properties and what is trapezoid then we will not be able to answer the given question.
Some properties of trapezoid
the base angles of isosceles triangle are equal Two sides are parallelAnswer 4 :-
Well, The answer is very easy that if we don't know anything regarding the trapezoid then we will not be able to any question based on it and if we have incomplete knowledge about it then we will able to solve it but we always got incorrect answers most probably.

Mrs. Thomas car averages 23 miles per gallon. How many gallons of gasoline will she need in order to make the round trip ? If the price of gasoline is $2.13 per gallon, what is the cost of the gasoline for the entire trip?
In addition to paying for the gasoline, Mrs. Thomas must also pay $13.92 fo her lunch and $32.98 for her dinner. What is the total amount of her meal expenses?
a. What is the total amount of her gasoline and meal expenses?
b. What operation did you use to figure it out ?
Answers
Answer:
a. $70.43
b. 23.43 + 13.92 + 32.98 = t (UNSURE)
Step-by-step explanation:
Since Mrs. Thomas is driving 231 miles using 23 miles per gallon, let's start by dividing 231 by 23
[tex]\frac{231}{23} = 10.043....[/tex]
We need to round 10.043... to 11 because you can't get part of a gallon.
Now, we need to multiply 2.13 by 11 to get the total amount of money for gasoline.
[tex]11 * 2.13 = 23.43[/tex]$
We also have the aditional meal expenses, which are $13.92 and $32.98.
We can use an equation to solve. Our total amount will be represented by t.
[tex]23.43 + 13.92 + 32.98 = t[/tex]
[tex]t = 70.43[/tex]

Answer:
f(x)=2x−5 if x≤−3
Since the value of x is -3, the first function will be the correct option.
Step-by-step explanation:
The given function is -
f(x)=2x−5 if x≤−3
f(x)=−3x+4 if x>−3
Now we have to evaluate f(-3).
Since we have to calculate the value of f at x = -3, we have to choose the first function.
That is f(x) = 2x - 5.
Hence,
f(−3)=2∗(−3)−5=−6−5=−11
Therefore we have the value
f(−3)=−11
Since the domain of the function is divided into two parts, we have to choose any one function for a given value of x,
For values of x less than or equal to -3, we will use the first function. That is,
f(x)=2x−5 for all x∈(−∞,−3]
And for values of x greater than -3, we will use the second function. That means,
f(x)=−3x+4 for all x∈(−3,∞)

Answers
Answer:
a) rise 5, run 5, slope 1
b) rise 10, run 5, slope 2
Step-by-step explanation:
The rise is the vertical difference between the points. It is the length of the vertical side of the triangle you have drawn. You can determine that length by counting grid squares or by finding the difference of the y-coordinates of the points.
The run is the horizontal difference between the points. It is the length of the horizontal side of the triangle you have drawn. You can determine that length by counting grid squares or by finding the difference of the x-coordinates of the points.
a)rise = 5; run = 5. (counting grid squares)
slope = rise/run = 5/5 = 1
__
b)rise = 10; run = 5. (taking coordinate differences: 5-(-5) = 10; 4-(-1) = 5)
slope = rise/run = 10/5 = 2

The Simplified polynomial expression in the standard form which represents the area of the given rectangle is,
[tex]2x^2+6x-8[/tex]
What is area of rectangle?The area of rectangle is the product of its length and width. It can be given as,
[tex]A=a\times b[/tex]
Here, (a) is the length of the rectangle and (b) is the width of the rectangle.
Given information-
One side of the rectangle is labeled as 2x-2.
Another side of the rectangle is labeled as x+4.
The image of the rectangle is attached below.
Let (l) is the length of the rectangle and (w) is the width of the rectangle.
In the below image, the length of the rectangle is,
[tex]l=4x+2[/tex]
The width of the rectangle is,
[tex]w=2x-2[/tex]
The area of the rectangle is the product of its length and width. Thus the area of the given rectangle is,
[tex]A=l\times w\\[/tex]
Put the values in the above expression as,
[tex]A=(x+4)\times(2x-2)\\A=2x^2+8x-2x-8\\A=2x^2+6x-8[/tex]

Since it is 2.5 hours of work, it will cost 35 * 2.5, but we need to include the flat rate so we get the expression

Answers
The cost of purchasing the number of shirts after discount and sale tax is $40.3125.
What is the percentage?The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.
The discount is 25%.
The total price before the coupon is $50.

What is the equation of the line that passes through the point (3,5) and has a slope of 2?
Answers
Answer:
y=2x-1
Step-by-step explanation:
The equation for a line (slope-intercept form) is:
y=mx+b
m: slope
b: y-intercept
x and y: (x, y) coordinate pair
In this scenario, since we are given the slope and a point on the line, we can solve for the y-intercept:
y=2x+b
5=2(3)+b
5=6+b
Subtract 6 from both sides
b=-1
Therefore the equation of the line is:
y=2x-1
