Answer:
It turns out that knowing all four sides of two quadrilaterals are congruent is not enough to conclude that the quadrilaterals are congruent. Unlike with triangles, some information about angles is needed in order to conclude that two quadrilaterals are congruent. I will give you the video that might be helpful. I dont own the video but i hope it helps you . <3

The scale from the drawing to the actual ramp is 2cm to 12in. What is the area of the actual side of the ramp?
The scale is 2 cm to 12 in so the actual length of the shorter side is 12 in, and the actual side of the longer side is (8/2)×12=48 in. So, the actual area of the ramp is (1/2)×12×48=288 Sq. in.
Scale used to convert the dimensions from drawing to actual is,
2 cm : 12 in
Height of the ramp in a skateboard park = 2 cm
Therefore, actual height 'x' of the ramp will be,
[tex]\frac{2}{12}=\frac{2}{x}[/tex]
x = 12 inches
Since, measure of the base of the ramp = 8 cm
Length of the base 'y' of the actual ramp will be,
[tex]\frac{2}{12}=\frac{8}{y}[/tex]
y = [tex]\frac{8\times 12}{2}[/tex]
y = 48 inches
Area of a triangle = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]
= [tex]\frac{1}{2}(48)(2)[/tex]
= 48 square inches

The correct option is (C).
What is strategy?
Strategy is an action that managers take to attain one or more of the organization's goals. Strategy can also be defined as “A general direction set for the company and its various components to achieve a desired state in the future. Strategy results from the detailed strategic planning process”.

Find the area of the following quadrilateral.
Answer: 480
Step-by-step explanation:
The quadrilateral ABCD is a trapezium
The formula for area of trapezium is
Area of trapezium = 1/2 × (parallel side 1 + parallel side 2) × h
So we can place the given values into the formula.
We get
Area = 1/2 × (9+15) × 40
Area = 1/2 × 24 × 40
By multiplying all of them we get
Area = 480cm

Step-by-step explanation:
FG = GH
9x+15 = 5x+4
Subtract 5x from each side
9x+15-5x = 5x+4-5x
4x+15 = 4
Subtract 15 from each side
4x+15-15 = 4-15
4x = -11
Divide by 4
4x/4 = -11/4
x = -11/4
FG = 9x+15
FG = 9*(-11/4) +15
= -99/4+15
-99/4 + 60/4
= -39/4
= -9 3/4

The straight line ax+by=1passes through the points (1,4)and (3,1).Find the values of a and b?
Answer:
a= 3/11
b = 2/11
Step-by-step explanation:
a(1) + b(4) = 1
a + 4b = 1
a(3) + b(1) = 1
3a + b = 1
b = 1-3a
a + 4(1-3a) = 1
a+ 4-12a = 1
-11a = -3
a = 3/11
b = 1-3(3/11)
b= 2/11
The value of a and b are 3/11 and 2/11 respectively.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
We have been given that the straight line ax+by=1 passes through the points (1,4)and (3,1).
Thus, the equation of the straight line passing through the point ( 3,1 )
a(3) + b(1) = 1
3a + b = 1
b = 1-3a
Thus, the equation of the straight line passing through the point(1,4)
a(1) + b(4) = 1
a + 4b = 1
Now substitute the value of b;
a + 4(1-3a) = 1
a+ 4-12a = 1
-11a = -3
a = 3/11
Then b = 1-3(3/11)
b= 2/11
Hence, the value of a and b are 3/11 and 2/11 respectively.

[tex]\displaystyle y = Atan(Bx - C) + D \\ \\ \boxed{y = tan\:(\frac{1}{3}x + \frac{\pi}{6}) - 1} \\ \\ Vertical\:Shift \hookrightarrow D \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \\ Wavelength\:[Period] \hookrightarrow \frac{\pi}{B} \\ Amplitude \hookrightarrow |A| \\ \\ Vertical\:Shift \hookrightarrow -1 \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \hookrightarrow \boxed{-\frac{\pi}{2}} \hookrightarrow \frac{-\frac{\pi}{6}}{\frac{1}{3}} \\ Wavelength\:[Period] \hookrightarrow \frac{\pi}{B} \hookrightarrow \boxed{3\pi} \hookrightarrow \frac{\pi}{\frac{1}{3}} \\ Amplitude \hookrightarrow N/A[/tex]
Here is all the information you will need. Now, what you need to know is that ALL tangent, secant, cosecant, and cotangent functions have NO amplitudes. Second, to find the period in this case, you need to take a look at the distanse between each vertical asymptote. Now, accourding to this graph, on a universal scale of [tex]\displaystyle \frac{\pi}{4}[/tex] with a range of [tex]\displaystyle -2\pi\:to\:2\pi,[/tex] the vertical asymptotes are [tex]\displaystyle -2\pi = x\:and\:\pi = x.[/tex] From here, you will then find the distanse between these asymptotes by simply perfourming the operation of Deduction, and doing that will give you [tex]\displaystyle \boxed{3\pi} = \pi + 2\pi.[/tex] So, the period of this function is [tex]\displaystyle 3\pi.[/tex] Now, you will instantly get the jist of the horisontal shift by looking at the above formula. Just keep in mind that the −C gives you the OPPOCITE TERMS OF WHAT THEY REALLY ARE, so you must pay cloce attention to what is given to you inside those parentheses. Finally, the midline is the centre of your graph, also known as the vertical shift, which in this case is at [tex]\displaystyle y = -1.[/tex]
Well, that just about wraps it up. Now that everything has been explained, you should understand it better. If you still have questions, do not hesitate to comment any you have.
