Here's the solution :
1. The given figure is of a Rectangle, and we know that diagnonals of a Rectangle bisects each other.
so, PR = 2 × PT
that is :
PR = 2 × 10 = 20 unitsand both the diagnonals of a Rectangle are equal,
PR = QS = 20 units2. let's take the length of PQ = x and QR = y
Angle RPS = Angle PRQ = 60°
(because they form pair of Alternate Interior angles, which are equal)
By using trigonometry :
[tex] \sin(60) = \dfrac{x}{20} [/tex][tex] \dfrac{ \sqrt{3} }{2} = \dfrac{x}{20} [/tex][tex]x = \dfrac{20 \times \sqrt{3} }{ {2} } [/tex][tex]x = 10 \sqrt{3} \: \: units[/tex]similarly,
[tex] \cos(60) = \dfrac{y}{20} [/tex][tex] \dfrac{1}{2} = \dfrac{y}{20} [/tex][tex]y = \dfrac{20}{2} [/tex][tex]y = 10 \: \: units[/tex]And now, we know that area of triangle PQR is equal to :
[tex] \dfrac{1}{2} \times base \times height[/tex][tex] \dfrac{1}{2} \times x \times y[/tex][tex] \dfrac{1}{2} \times 10 \sqrt{3} \times 10[/tex][tex]50 \sqrt{3} \: \: unit {}^{2}[/tex]3. Area of Rectangle PQRS :
[tex]length \times width[/tex][tex]x \times y[/tex][tex]10 \times 10 \sqrt{ 3} [/tex][tex]100 \sqrt{3} \: \: unit {}^{2} [/tex]Related Questions

Step-by-step explanation:
Value of x9x - 2 = 5x + 54
9x - 5x = 54 + 2
4x = 56
x = 14
value of y(9x - 2) + (10y + 6) = 180
(9 · 14 - 2) + 10y + 6 = 180
126 - 2 + 10y + 6 = 180
130 + 10y = 180
10y = 180 - 130
10y = 50
y = 5

Answer:
-8 <_ x < -3
-7 <_ y < -2
Step-by-step explanation:
closed dot means it includes that number so in this case x is least than or equal to -8 and open dot means it doesn't include that value so x is less than -3 and does NOT include -3
and for the y value it's pretty self explanatory if u just count it (i might be off by a little cuz the photo quality is kinda fuzzy but i hope u get the gist!)

you would set up the equation like this

then you could add 8 to each side
8x = 7x + 16
then subtract 7x from each side

Answers
Answer:
c = -1/4
e = 1 2/5
Step-by-step explanation:
4c - 5 = -6
add 5 to both sides
4c = -1
divide each side by 4
c = -1/4
5e + 2 = 9
subtract 2 from both sides
5e = 7
divide both sides by 5
e = 1 2/5

Answer:
c = -1/4
e = 7/5
Step-by-step explanation:

For Allison's lemonade recipe, 16 lemons are required to make 12 cups of lemonade. At what rate are lemons being used in lemons per cup of lemonade?
Answers
Answer:
4/3 lemons
Step-by-step explanation:
For 16 lemons per 12 cups, simplify the ratio to 4 lemons per 3 cups.
The required rate of lemon per cup of lemonade is 1.34 lemons per cup.
Given that,
For Allison's lemonade recipe, 16 lemons are required to make 12 cups of lemonade. At what rate are lemons being used in lemons per cup of lemonade to be determined.
The rate of change is defined as the change in value with the rest of the time is called the rate of change.
What is the Ratio?The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.
Since
Let the rate of lemon per cup of lemonade is x,
Total lemon = 16
To a cup of lemonade = 12
Rate of lemon per cup of lemonade
x = 16/12
x = 1.34
Thus, the required rate of lemon per cup of lemonade is 1.34 lemons per cup.

if e^f(x)=1+x^2, then f(x)=
Answers
Step-by-step explanation:
point dene ke liye sukriya tumhara dost
Answer:
[tex]\displaystyle f(x) = \ln\left( 1 + x^2\right)[/tex]
Step-by-step explanation:
We are given that:
[tex]\displaystyle e^{f(x)} = 1 + x^2[/tex]
And we want to find f(x).
We can take the natural log of both sides:
[tex]\displaystyle \ln\left(e^{f(x)}\right) = \ln\left( 1 + x^2\right)[/tex]
Recall that ln(aᵇ) = bln(a). Hence:
[tex]\displaystyle f(x) \ln(e) = \ln\left ( 1 + x^2\right)[/tex]
By definition ln(e) = 1. Therefore:
[tex]\displaystyle f(x) = \ln\left( 1 + x^2\right)[/tex]
Which angles are non-adjacent with <8? (Mark all that apply)
<2

Answers
Answer: Every answer choice is to be selected
Explanation:
The following angles are adjacent to angle 8
angle 7angle 9Adjacent angles share a common line segment, line, or ray. Think of it like a shared wall. The other remaining angles are non-adjacent even though something like angle 6 shares a common vertex with angle 8, they don't share a common wall. In a sense, the person living in apartment 6 isn't a direct next door neighbor to the person in apartment 8.
So that's why we select angles 2, 4, 5, 1 and 3 as our answers. In short, we click each box to select all answer options.
