The vertices of a rectangle are W(1,2), X(4,2), 7(4, -3), and Z(1, -3). Find the perimeter of the
rectangle. Use words, numbers, or models to justify your answer.
Answer:
16
Step-by-step explanation:
We could use the distance formula to find the distance between the points in this problem, but when we look we see that the sides of the rectangle are parallel to the x and y-axis for each pair of sides. The first two points have a distance of 3 because 4-1=3. Since it is a rectangle, the opposite side will have the same length. For the sides perpendicular, we look at the points with the same x coordinate. Using (4,2) and (4,-3), we can calculate the length of the side by finding the distance by adding the absolute values of the y coordinate. 2+3=5. This means that the triangle has two sides with a length of 5 and two sides with a length of 3. Adding these together, 5+5+3+3 = 16.

In the figure, ABCD is a rhombus.BG and DCG are straight lines
Find CAD
Find ACG
Answer:
Below in bold.
Step-by-step explanation:
1) as ABCD is a rhombuc AC bisects < BAD and < BCD .
Therefore < CAD = 1/2 * 104 = 52 degrees.
2) < ACG = < ADC + < CAD ( External angle of triangle theorem)
Therfore < ACG = 76 + 52 = 128 degrees.

120
What is the answer?
Step-by-step explanation:
120° + 20° + x = 180° ( sum of interior angle. of triangle is 180°)
140° + x = 180°
x = 180° - 140°
x = 40°
Now
y + x = 180° ( supplementary angle)
y + 40° = 180°
y = 180° - 40°
y = 140°
The angle measure of y is 140°.
What is an angle measure?When two lines or rays intersect at a single point, an angle is created. The vertex is the term for the shared point. An angle measure in geometry is the length of the angle created by two rays or arms meeting at a common vertex.
Given:
The three angles of a triangle are 120°, 20° and x.
And we know,
the sum of the interior angle of the triangle is 180°.
120° + 20° + x = 180°
140° + x = 180°
x = 180° - 140°
angle measure of x = 40°
Now:
Here, x and y are supplementary angles.
Supplementary angles are two angles whose measures add up to 180°
y + x = 180°
y + 40° = 180°
y = 180° - 40°
y = 140°
Therefore, the value of y is 140°.

Write the equation of a line of the table below.
Pls help will give brainliest
Answer:
slope: 5
y-intercept: 0
Equation: [tex]y=5x[/tex]
Step-by-step explanation:
First, lets find the slope.
Every time we have an increase in [tex]x[/tex], we have an increase in [tex]y[/tex].
To find that change, we will divide the changes in [tex]y[/tex] using two points.
I will be using the points [tex](1,5), (2,10)[/tex]
[tex]\frac{10-5}{2-1}[/tex]
[tex]=5/1[/tex]
[tex]=5[/tex]
Therefore, the slope is 5.
Next, lets find the y-intercept. The y-intercept is where the line goes through the y-axis.
We can go back 1 x-value (since when x = 1, y = 5)
Subtracting our slope (5) from the y-value for 1, we get:
[tex]y=0[/tex]
Therefore, the y-intercept is 0.
Finally, lets find the equation.
Linear equations are in the form [tex]y=mx+b[/tex], where m is the slope and b is the y-intercept.
Plugging those values in we get: [tex]y=5x+0[/tex]
Which will be simplified down to [tex]y=5x[/tex]

The total cost of 8 sharpeners and 3 sketchbooks is $26.05. If the cost of a sharpener is $a, and a sketchbook is $1.90 more expensive,
find A. Give your answer to two decimal places.
Answer:
1.85
Step-by-step explanation:
So, s (sketchbook) is a+1.90.
8a+ 3(a+1.90)=26.05
8a+3a+5.7=26.05
11a=20.35
a=1.85
Check:
8x1.85=14.8
s=11.25
Answer:
A= 1.85
Step-by-step explanation:
I made an equasion
8(a) + 3(a+1.90) = 26.05
distributed
8a+ 3a + 5.70 = 26.05
Added
11a+ 5.70= 26.05
subtracted
11a= 20.35

please help
Answer:
90 is the orrect answer because I said so
Step-by-step explanation:
Answer:
The answer is a = 99
Step-by-step explanation:
We can solve this using ratios
First we set up the equation:
[tex]\frac{a}{90}= \frac{110}{100}[/tex]
Then cross-multiply:
[tex]100 * a = 90 * 110[/tex]
Simplify:
[tex]100 * a = 9,900[/tex]
Divide both sides by 100:
[tex]a = 99[/tex]
Ta-Da! The answer is a = 99

Answer:
So there are 2 pi radians in one revolution and since there are also 360 degrees in one revolution, this gives us a way to convert from radians to degrees. 2 pi radians equals 360 degrees or you can divide both sides by 2 and use pi radians equals 180 degrees.
