An architect designs two similar triangular patios. The first patio has angle measures of (x + 5)°, (y + 15)°, and 80°. The second patio has angle measures of (x + 25)°, 40°, and 60°. Find the values of x and y. please answer fast! i just need this one!
Answer:
x = 55° and y = 25°
Step-by-step explanation:
Since we have two triangular patios with angles (x + 5)°, (y + 15)°, and 80° and the second patio has angles, (x + 25)°, 40°, and 60° respectively, and the sum of angles in a triangle is 180, we have that,
(x + 5)° + (y + 15)° + 80° = 180° and
(x + 25)° + 40° + 60° = 180°
Simplifying both expressions, we have
x + 5° + y + 15° + 80° = 180° and
x + 25° + 40° + 60° = 180°
collecting like terms, we have
x + y + 5° + 15° + 80° = 180° and
x + 25° + 40° + 60° = 180°
Adding the like terms, we have
x + y + 100° = 180° and
x + 125° = 180°
So,
x + y = 180° - 100° and
x = 180° - 125°
Thus,
x + y = 80° and
x = 55°
So, y = 80° - x = 80° - 55° = 25°
So, x = 55° and y = 25°

Write the standard equation of the circle if the center is (-1,2), and a point on the circle is (2,6).
Plz help me someone
Answer:
(x+1)²+(y-2)² = 25
Step-by-step explanation:
Standard equation of the circle is expressed as;
(x-a)²+(y-b)² = r²
(a,b) is the center of the circle
r is the radius
Get the radius
r = √(x2-x1)²+(y2-y1)²
r = √(2+1)²+(6-2)²
r = √3²+4²
r = √9+16
r = √25
r = 5
Substitute into the formula
(x-a)²+(y-b)² = r²
a = -1, b = 2, r = 5
(x-(-1))²+(y-2)² = 5²
(x+1)²+(y-2)² = 25
This gives the required equation
Angle A is x. Angle B is 20 more than angle A. If angles A and B are supplementary angles, find the value of x.
Answer:
9
Step-by-step explanation:
that's because angle B is twice angle A in which they add up to 180 because they are supplementary angles
20x=180
divide both sides by 20

Answer:
( x + 2 )² + ( y - 1 )² = 25
Step-by-step explanation:
Circle equation - ( x - h )² + ( y - k )² = r²
Important notes:
(h,k) = center
r = radius
The first step would be to find the center
( it's hard to explain how to find the center point virtually but the center point is at (-2,1) )
Like stated before ( h , k ) = center point
* replace center point with (-2,1) *
( h , k ) = ( -2 , 1 )
h = -2
k = 1
* plug in the h and k values into the circle equation *
now we have ( x - ( -2) )² + ( y - 1 )²
Now to find the radius
We can find the radius by using the distance formula with the center point and any point on the circle's outline
The point chosen can vary but i chose (3,1)
Because the y value of the chosen point and the y value of the center are the same we can simply subtract the larger x value by the smaller x value to find the radius
3 - (-2)
the two negative signs cancel out
3 + 2 = 5
So the radius equals 5
* plug in the value of the radius into the equation *
Now we have
( x - (-2) )² + ( y - 1 )² = 5²
our final step is to simplify
- (-2) the two negative signs cancel out and it turns into +2
5² = 25
Our final answer would be ( x + 2 )² + ( y - 1 )² = 25

At the grocery store, marilyn bought 4 apples and 7 oranges. select two ways she could write the ration of apples to oranges.
A. 7:4
B. 4 to 7
C. 4:11
D. 4:7
E. 7 to 4
(they are optional)
Given:
Number of apples purchased = 4
Number of oranges purchased = 7
To find:
The ratio of apples to oranges in two ways.
Solution:
Ratio of apples to oranges is:
[tex]Ratio=\dfrac{Apples}{Oranges}[/tex]
After substituting the given values, we get
[tex]Ratio=\dfrac{4}{7}[/tex]
[tex]Ratio=4:7[/tex]
[tex]Ratio=4\text{ to }7[/tex]
Therefore, the correct options are B and D.

Answer:
A. About 1/3 of the people prefer pie without ice cream
Step-by-step explanation:
We know there were 80 people surveyed, so that's our denominator. Pie without ice cream is the bottom row. 15 + 12 = 27. 27/80 = 0.3375, which is 33.75% (multiply 0.3375 by 100), which is about 1/3.
B is wrong, because the blueberry pie numbers are not double the cherry pie numbers
C is wrong because cherry with ice cream is 24, blueberry without is 15
D is wrong because the ratio of blueberry to cherry is 44:36, and with ice cream to without is 53:27
An 18-ft tall tree casts a shadow of 25 feet. Find the angle of elevation of the sun.
Answer:
46.05degrees
Step-by-step explanation:
Given the following
Height of tree = 18ft (Opposite)
length of shadow = 25ft (hypotenuse)
Required
Angle of elevation
Sin theta = opp/hyp
Sin x = 18/25
sin x = 0.72
x = arcsin(0.72)
x = 46.05
Hence the angle of elevation of the sun is 46.05degrees

Answer:
Part A A. 400 sq ft.
Part B A. 509 sq ft
Step-by-step explanation:
Part A
Area of square = side squared
Since all the sides of the square are congruent and the perimeter is 80, then the length of each side is 80/4 = 20
A = 20^2 = 400 sq ft
Part B
C = πd
80 =
80/π = d
r = d/2 = 80/2π = 40/π
A = πr^2 = π(40/π)^2
= 1600π/π^2 = 1600/π = 1600/3.14 = 509 sq ft

I need help plzzzzzzz help24+4x=6x+2
Answer:
x = 11
Step-by-step explanation:
24+4x=6x+2
substract 2x from both sides 4x-4x and 6x -4x
24 = 2x + 2
Substract 2 from both sides 24-2 and 2-2
22 = 2x
Divide by 2 to both sides 22/2 and 2x/2
x = 11
Graph the equation using the point and the slope.
y-4= 1/2(x-4)
Answer:
Look at the explanation
Step-by-step explanation:
From this equation, we know our point slope form: y-4= 1/2(x-4)
From here, we also know our point: (4,4)
Our slope is 1/2
We first plot (4,4) on the graph. Then we graph the slope by moving one space up from (4,4) and moving over two spaces.
Our graph would look something like this:
Find the volume of the cylinder
What is the exact volume in terms ofx?
What is the approximate volume using 3 14 forx?
9514 1404 393
Answer:
5000π mm³ ≈ 15,700 mm³
Step-by-step explanation:
The volume of the cylinder is given by the formula ...
V = πr²h
For the given radius and height, the volume is ...
V = π(10 mm)²(50 mm) = 5000π mm³
Using 3.14 for π, the volume is ...
5000(3.14) mm³ = 15,700 mm³
