Step-by-step explanation:
set up a proportion:
24 = 32
33 32+x
24(32 + x) = 32(33)
768 + 24x = 1056
24x = 288
x = 12

Find the values of x and y. Pls helpI’m helpless at math
Answer:
x = 1 [tex]y=\frac{\sqrt{3}}{2}[/tex]Step-by-step explanation:
From the given right-angle triangle
The angle = ∠60°
The adjacent to the angle ∠60° is 1/2. The opposite to the angle ∠60° is y.The hypotenuse = x
Determining the value of x:
Using the trigonometric ratio
cos 60° = adjacent / hypotenuse
substituting adjacent = 1/2 and hypotenuse = x
[tex]cos\:60^{\circ }=\:\:\frac{\frac{1}{2}}{x}[/tex]
[tex]\cos \left(60^{\circ \:}\right)=\frac{1}{2x}[/tex]
[tex]\frac{1}{2}=\frac{1}{2x}[/tex] ∵ cos (60°) = 1/2
[tex]2x=2[/tex]
Dividing both sides by 2
[tex]\frac{2x}{2}=\frac{2}{2}[/tex]
Simplify
[tex]x=1[/tex]
Thus, the value of hypotenuse x is:
x = 1
Determining the value of y:
Using the trigonometric ratio
sin 60° = opposite / hypotenuse
As we have already determined the value of hypotenuse x = 1
substituting opposite = y and hypotenuse = 1
sin 60° = y/1
y = 1 × sin 60°
[tex]y=\frac{\sqrt{3}}{2}[/tex] ∵ [tex]\sin \left(60^{\circ \:}\right)=\frac{\sqrt{3}}{2}[/tex]
Therefore, the value of y is:
[tex]y=\frac{\sqrt{3}}{2}[/tex]
Summary:
x = 1 [tex]y=\frac{\sqrt{3}}{2}[/tex]use the determinant method to find the area of a triangle ABC with vertices at A (1,6) B (4,2) and C (-3,3)
Answer:
Area of triangle is 12.5
Step-by-step explanation:
We need to use the determinant method to find the area of a triangle ABC with vertices at A (1,6) B (4,2) and C (-3,3)
The formula used is: [tex]Area=\pm \frac{1}{2}\left|\begin{array}{ccc}x_1&y_1&1\\x_2&y_2&1\\x_3&y_3&1\end{array}\right|[/tex]
We are given:
[tex]x_1=1,y_1=6,x_2=4,y_2=2,x_3=-3,y_3=3[/tex]
Putting values and finding area
[tex]Area=\frac{1}{2}\left|\begin{array}{ccc}x_1&y_1&1\\x_2&y_2&1\\x_3&y_3&1\end{array}\right|\\Area=\frac{1}{2}\left|\begin{array}{ccc}1&6&1\\4&2&1\\-3&3&1\end{array}\right|\\Area=\frac{1}{2}(1\left|\begin{array}{cc}2&1\\3&1\end{array}\right|-6\left|\begin{array}{cc}4&1\\-3&1\end{array}\right|+1\left|\begin{array}{cc}4&2\\-3&3\end{array}\right| )\\Area=\frac{1}{2}(1(2-3)-6(4-(-3))+1(12-(-6)))\\Area= \frac{1}{2}(1(-1)-6(4+3)+1(12+6))\\Area= \frac{1}{2}(1(-1)-6(7)+1(18))\\Area= \frac{1}{2}(-1-42+18)\\[/tex]
[tex]Area=\frac{1}{2}(-25)\\Area=-12.5\\[/tex]
We take mode of -12.5 i.e. |-12.5| because area can't be negative.
[tex]Now, \\Area=|-12.5|\\Area=12.5[/tex]
So, Area of triangle is 12.5

John is measuring a piece of glass to fit in a triangular frame. He can only remember
two sides of the frame, which are 6 centimeters and 11 centimeters. Between what
two numbers must the third side of the frame fall?
A. X < 17
B. X > 5
C.5< X < 17
D. 5 ≤ X ≤ 17
Answer: (c)
Step-by-step explanation:
Given
length of two sides of a triangle is 6 cm and 11 cm
In a triangle length of the third side lies between the sum and subtraction of the other two sides
Suppose x is the length of the third side so

11. Find mZJHI.
Answer:
JHI = 23°
Step-by-step explanation:
Since it's a rectangle it has 4 right angles.
90= 3x + 2 + 12x -17
90= 15x -15
105= 15x
x=7°
So HJI would be 12*7 -17 = 67°
Knowing that the sum of the angles of a triangle is 180°,
67° + 90°+ JHI= 180°
JHI = 23°
Answer:
Step-by-step explanation:
we have 2 equations that we can set equal to 90. that way, we can find x and then solve the equations for themselves. angle JHI is equal to GJK, which is an angle we can easily find. here is my work:
(3x + 2) + (12x - 17) = 90
15x - 15 = 90
+ 15 + 15
15x = 105
x = 7
3(7) + 2
21 + 2
GJK = 23
so, since the two angles are congruent, that means that angle JHI = 23 degrees

The correct answer is 34°
They are supplementary angles (connect with a straight line) which means that their angles add up to 180° so:

determine a similarity transformation that maps the primage to the image.
Answer:
Step-by-step explanation:
From the figure attached,
ΔABC has been dilated to form another triangle ΔA'B'C'.
Therefore, ΔA'B'C' is the image triangle of preimage ΔABC.
Coordinates of preimage ΔABC are,
A(3, 3), B(2, 0) and C(5, 2)
Coordinates of ΔA'B'C',
A'(6, 6), B'(0, 4) and C'(10, 4)
Since, dilation of a triangle is a similarity transformation which produces the similar image of the preimage.
Rule for the dilation is,
(x, y) → (kx, ky)
Here, k = scale factor of dilation
By this rule,
A(3, 3) → A'(6, 6)
→ A'(2×3, 2×3)
Scale factor = 2
Therefore, "Triangle (ABC) is dilated by a scale factor 2 about the origin to form triangle (A'B'C') ".

bob is 12 years younger than john. john is 3 times as old as bob. how old are bob and john.
Answer:
John will be 16 years old when he is twice as old as his brother, which will then be 8.
Step-by-step explanation:
Currently John is 12, and is three times as old as his brother thus, his brother is 12 divided by 3, which is 4 years old.
Thus when John is 12, his brother is 4. There is thus a 8 year difference between the two brothers.
So we can write a small equation to solve John’s age when he will be twice as old.
John’s age = X
John’s Brothers age = X - 8
Thus : X - 8 = X/2, John’s age minus the difference of 8 years must equal John’s age divided by 2, to make John twice as old as his brother.
X - 8 = x/2
X = X/2 + 8
(2*X)/2 = (X/2) + (16/2) - Place all numbers as fractions of 2 by multiplying x 2
2*X = X + 16
2*X -X = 16
X+X -X = 16
X = 16
John’s age will be 16 when he is twice as old as his brother which will be 8.
John : 16 - 12 = 4 : Subtract current Age
His Brother: 8 - 4 = 4 : Subtract current Age
In 4 years time John will be twice as old as his brother
16 = 8 * 2
The age of Bob and John is 6 and 18 respectively.
According to the question;
Bob is 12 years younger than john.In essence, x = y - 12........eqn(1)and
John is 3 times as old as Boby = 3x...........eqn(2)where; x = Bob's age and y = John's age.
By substituting 3x for y in equation (1). We have;
x = 3x -12x -3x = -12-2x = -12x = 6.Therefore, since, x = 6;
y = 3 × 6 = 18.Ultimately, The age of Bob and John is 6 and 18 respectively.

Answer:
Integers are Not Closed under Division
Step-by-step explanation:
Answer:
Integers are Not Closed under Division.
Step-by-step explanation:
There are three integers between-2 and 2. ... The set of integers is closed under addition, subtraction, and multiplication because when I add, subtract, or multiply any integers, the result is always an integer. The set is not closed under division because 2 + 4 = 0.5, and 0.5 is not an integer. The integers are "closed" under addition, multiplication and subtraction, but NOT under division ( 9 ÷ 2 = 4½). (a fraction) between two integers. Integers are rational numbers since 5 can be written as the fraction 5/1.
