The measure of x from the triangle is x = 4
Define the Triangle.A planar figure or polygon having three sides and three angles is called a triangle.
The internal angles of a triangle, which has three vertices, add up to 180 degrees.
Assume the triangle is ABC, with A + B + C equaling 180 degrees.
Triangle area equals (1/2) × Length x Base.
About a right triangle
According to the Pythagoras Theorem, If a2 + b2 = c2, then the hypotenuse2 = base 2 + height 2, making it a right triangle.
If a2 + b2 c2, the triangle is an acute triangle.
If a2 + b2 > c2, the triangle is sharp.
Given the data,
Let's use ABC to depict the triangle.
Now, the triangle's sides are measured in units of AB and y.
x units = BC
Moreover, AC = 8 units.
The trigonometric relationships show that sin = opposite / hypotenuse.
Hence, the definition of sin 30° is x / 8
With simplification, we have (1/2) = x / 8
8 is multiplied twice, giving us x = 8/2 x = 4 units.
Hence , the sides of the triangle are solved

At the end of a snow storm, Elijah saw there was a lot of snow on his front lawn. The temperature increased and the snow began to melt at a steady rate. There was a depth of 18 inches of snow on the lawn when the storm ended and then it started melting at a rate of 1.5 inches per hour. Write an equation for S, in terms of t, representing the depth of snow on Elijah's lawn, in inches, t hours after the snow stopped falling.
Answers
Answer:
S = 18 - 1.5t

4. If the area of a rectangle is 6 m2, then the dimensions must be 2 meters by 3 meters. oh
Answers
Answer:
False.
Step-by-step explanation:
The formula that is used to find the area of a rectangle is given by :
A = l×b
Where,
l is length and b is breadth
If area of a rectangle is 6m², it means we need to find the factors of 6. The factors of 6 are 2 and 3. If we multiply 2 and 3, we get 6.
Other possibility can be 1 m by 6 m because if we muliply 1 m and 6 m, we get 6m².
It means there are more than one possibiliy about the length and breadth of the rectangle.
Hence, the given statement is not true.
The average number of customers that visited a particular store during the past year is 200 per day and a standard deviation of 25 customers per day. The probability that x>200 is:
Answers
Answer:
0.5
Step-by-step explanation:
Considering we are given a mean and standard deviation, the distribution of the data is likely to be a normal or Gaussian distribution, i.e. a symmetrical, bell-shaped distribution of probability density, peaked at the mean;
Such a distribution has 0.5 probability each side of the mean;
So, if the mean is 200 then, the probability that the number of customers is greater than 200 (x > 200), according to this mean, is 0.5;
As a normal distribution is symmetrical, this is also the probability of a number of customers less than 200.
Yara have two rectangular gardens in her backyard the smaller garden is 1/2 foot long and 2/3 foot wide the larger Garden is 4 feet long and 5 feet wide what is the area of the small garden in square feet what is the area of the large garden in square feet
Answers
Given that :
Area of a rectangle is : A = l×b
For smaller garden,
Length, l = [tex]\dfrac{1}{2}\ \text{foot}[/tex]
Width, [tex]b=\dfrac{2}{3}\ \text{foot}[/tex]
Area of a smaller garden is :
[tex]A=\dfrac{1}{2}\times \dfrac{2}{3}\\\\A=0.34\ \text{foot}^2[/tex]
For larger garden,
length, l' = 4 feet
Width, b' = 5 feet
Area of a larger garden is :
[tex]A'=l'\times b'\\\\A'=4\times 5\\\\A'=20\ \text{feet}^2[/tex]
So, the area of a smaller garden is 0.34 sq ft and that of a larger garden is 20 sq ft.
Ms. Waters, the manager of Paradise Lake, just ordered a duck and goose food dispenser. She plans to use a paper cone to hold the pellets. The machine is set to dispense no more than 350 cm3 of food for each token. The cones are 12 cm. in diameter. How tall must the cone be to hold the food
Answers
Step-by-step explanation:
Equation for the volume of a cone is
V = (pi(r^2)h)/2
Plug in the known values to get
350 = (pi(6^2)h)/2
To find h, just isolate it by first dividing both sides by 2 and squaring 6 to get
175 = pi(36)h
Then, divide both sides by pi36 to get
h = 175/pi(36)

This figure has two intersecting lines and a ray. What is the value of x?
108°
72°
19°
37°
Answers
Answer: The answer is 37
Step-by-step explanation:
If you subtract 71 from 108 the answer is 37
Since the angles of (x + 71)º is opposite to the same vertex to the angle of 108º, it is found that x = 37º.
The ray generated two angles, xº and 71º.Adding these angles, there is an angle of (x + 71)º, which is opposite to the same vertex to the angle of 108º, meaning that they have the same measure.
Applying the equality:
[tex]x + 71 = 108[/tex]
[tex]x = 108 - 71[/tex]
[tex]x = 37[/tex]
Thus, x = 37º.

While reviewing last month's finances, Oscar noticed that he had spent $200 on a wedding cake and deposited $500 that he had earned from selling books to a used bookstore. Then, he again spent $127 to buy some new books. Which integer represents the change in Oscar's savings?
Answers
Answer:
$173
Step-by-step explanation:
Given the following :
Amount spent on wedding cake = $200
Amount deposited = $500
Amount spent on new books = $127
Change in savings :
Amount deposited - total amount spent
Total amount spent = ($200 + $127).= $327
Hence,
Change in saving = $500 - $327
= $173

A semicircle is drawn onto one of the shorter sides of a rectangle. The shorter side of the rectangle measures 4 centimeters. The area of the figure is 41.4 square centimeters.
What is the length of the longer side of the rectangle?
Use 3.14 for π.
Enter your answer as decimal in the box.
Answers
We are given that :
A semicircle is drawn onto the shorter side of rectangle.Shorter side of rectangle measures 4cm. i.e; the diameter of the circle is 4cmArea of the figure is 41.4 cm²Using Formulas:
Area of rectangle:
[tex] \quad\hookrightarrow\quad{\pmb{ \mathfrak {length\times breadth }}}[/tex]
Area of semicircle:
[tex] \quad\hookrightarrow\quad{\pmb{ \mathfrak{ \dfrac{\pi r^2 }{2}}}}[/tex]
We have to find the length of longer side of rectangle!Here, we can know that the figure is composed of one rectangle and one semicircle. Therefore by combining the areas of rectangle and circle and taking the length of rectangle as a variable , we will finds its value ;
[tex] \quad\dashrightarrow\quad \sf {Area_{\tiny { total}} = Area_{\tiny {rectangle}}+ Area_{\tiny {semicircle}}}[/tex]
[tex] \quad\dashrightarrow\quad \sf {A = ( l \times b ) + \dfrac{\pi r^2 }{2} }[/tex]
[tex] \quad\dashrightarrow\quad \sf {41.4 = ( l \times 4 ) +\dfrac{3.14\times 2^2}{2} }[/tex]
[tex] \quad\dashrightarrow\quad \sf { 41.4= ( l \times 4 )+ \dfrac{ 3.14\times 4}{2}}[/tex]
[tex] \quad\dashrightarrow\quad \sf { 41.4=( l \times 4 )+ \dfrac{12.56}{2}}[/tex]
[tex] \quad\dashrightarrow\quad \sf { 41.4= (l \times 4 )+ 6.28}[/tex]
[tex] \quad\dashrightarrow\quad \sf {l \times 4 = 41.4-6.28 }[/tex]
[tex] \quad\dashrightarrow\quad \sf { l\times 4 = 35.12}[/tex]
[tex] \quad\dashrightarrow\quad \sf { l =\dfrac{35.12}{4}}[/tex]
[tex] \quad\dashrightarrow\quad \underline{\underline{\pmb{\sf {l = 8.78\:cm}}} }[/tex]
The length of the longer side of the rectangle will be 8.78 cm.
What is the area?The area of a two - dimensional figure is the area that its perimeter encloses. The quantity of unit squares that occupy a closed figure's surface is its region.
On one of a rectangle's shorter sides, a semicircle is drawn. The rectangle's shorter side is 4 cm long. The figure has a surface area of 41.4 square centimeters.
Then the length of the rectangle is calculated as,
A = πr² / 2 + l × b
41.4 = (3.14 / 2) × (4/2)² + 4l
41.4 = 6.28 + 4
l = 8.78 cm
The length of the longer side of the rectangle will be 8.78 cm.

The theorem that proves that lines d and e are parallel to each other, given that <2 is congruent to <6 is: D. Converse of the alternate exterior angle theorem
When a transversal cuts across two parallel lines, there are special angles formed having relationship with each other.
For two lines to be parallel, such relationship must exist. That is what a converse theorem seeks to prove.
We are told that <2 is congruent to <6.Both angles are exterior angles that also lie opposite each other along the transversal. That makes them alternate exterior angles.<2 will be congruent to <6 if lines d and le are parallel to each other.Therefore, the theorem that proves that lines d and e are parallel to each other, given that <2 is congruent to <6 is: D.
