What are similar triangles?If two triangles' corresponding angles are congruent and their corresponding sides are proportional, they are said to be similar triangles. In other words, similar triangles have the same shape but may or may not be the same size. The triangles are congruent if their corresponding sides are also of identical length.
Corresponding sides of similar triangles are in the same ratio. The ratio of area of similar triangles is the same as the ratio of the square of any pair of their corresponding sides
Given data ,
Let the first triangle be represented as ΔIGJ
Let the second triangle be represented as ΔHGK
Now , K is the midpoint of GJ and H is the midpoint of GI
So , IH = GH and GK = KJ
And , the triangles ΔIGJ and ΔHGK are similar
So , corresponding sides of similar triangles are in the same ratio
Substituting the values in the equation , we get
The measure of HK = ( 1/2 ) measure of side IJ
And , ( z - 37 ) = ( 1/2 ) x ( z - 4 )
On simplifying the equation , we get
Multiply by 2 on both sides of the equation , we get
2z - 74 = z - 4
Subtracting z on both sides of the equation , we get
z - 74 = -4
Adding 74 on both sides of the equation , we get
z = 70
Hence , the value of z is 70

How do you find the mean median and mode in class 9?.
To find the mean, median and mode add up the values and divide, the value of set in middle of the list and identify the most number of times a number is repeated.
The sum of all observations divided by the total number of observations yields the arithmetic mean of a set of data. For illustration, a cricketer's five ODI scores are as follows: 12, 34, 45, 50, 24. We compute the arithmetic mean of the data using the mean formula in order to get his typical score in a game:
Mean = Sum of all observations/Number of observations
Mean = (12 + 34 + 45 + 50 + 24)/5
Mean = 165/5 = 33
The median of the data is the value of the middle observation after the data have been arranged in either ascending or descending order.
Take these numbers as an example: 4, 4, 6, 3, 2. Let's organize these numbers ascending: 2, 3, 4, 4, 6.
Median = (n + 1)/2th observation
A data mode is the value that appears the most frequently in the provided data, or the observation with the highest frequency.

The perimeter of a rectangular garden is 4.8 meters. Its length is twice its width. How wide is the garden? (Full Answer)
Answer:
0.8 meters is the width.
Step-by-step explanation:
Answer: 0.8
Step-by-step explanation: All you have to do is set the equation up so you're looking at the length being twice the width (which in equation form would be l=2w) then you say there is two lengths, so you have 4w. Then you add the original width to the lengths (2w) so you have 6w= 0.8

What are characteristics of perpendicular lines?.
The characteristics of perpendicular lines:
1) Perpendicular lines are intersecting lines.
2) The perpendicular lines are coplanar.
3) The perpendicular intersect at a 90° angle.
4) The product of slopes of perpendicular lines is -1.
We know that two lines are perpendicular to each other if they intersects and these two lines are inclined at angle 90°
Since these lines are inclined at 90° to each other, hence they create right angles.
Perpendicular lines are intersecting lines.
Also, the perpendicular lines are coplanar.
Mathematically, the perpendicular lines are represented by the symbol, ‘⊥‘.
If two lines l₁ and l₂ are perpendicular to each other then they are represented as l₁ ⊥ l₂.
The product of slopes of perpendicular lines is always -1.
Let m₁ be the slope of line l₁ and m₂ be the slope of line l₂.

What is the latest estimate for the likelihood of one or more M 6. 7 earthquakes in the Bay Area region before the year 2043?.
A 72 percent is the latest estimate for the likelihood of one or more M 6.7 earthquakes in the Bay Area region before the year 2043.
To estimate the likelihood of future earthquakes, scientists rely on a variety of techniques that help us understand the velocities and magnitudes of past earthquakes. Using the Global Positioning System (GPS) and other land surveys and geological techniques,scientists have determined how much current plate movement, totaling inches per year across the San Francisco Bay region, stresses these individuals. We were able to more accurately measure how well it disperses. Small earthquakes occur more frequently than large ones. There is a 98% chance that an earthquake of magnitude 6.0 or greater will occur before 2043. There is a 72% chance that at least one earthquake of magnitude 6.7 or greater will occur in the San Francisco Bay Area, and a 51% chance that at least one magnitude earthquake will occur. Therefore they concluded that there is a 72% chance (or probability) of at least one earthquake of magnitude 6.7 or greater occurring somewhere in the San Francisco Bay Area before 2043.

B is the midpoint of AC. AB - 6x + 1 and BC - 2x + 9. Find the length of AC
The length of AC in the line segment is 26 units.
How to find the length of a line segment?B is the midpoint of AC.
AB = 6x + 1
BC = 2x + 9
A midpoint is a point lying between two points and is in the middle of the line joining the two points.
Hence,
AB = BC
6x + 1 = 2x + 9
6x - 2x = 9 - 1
4x = 8
divide both sides by 4
x = 8 / 4
x = 2

What i the difference between 4 x 3 and 43? Prove your anwer and explain your thinking
The difference between 4 x 3 and 43 is that 4 x 3 is the mathematical operation of multiplying 4 and 3, which equals 12, while 43 is just a number.
The Mathematical OperationsThe difference between the expression "4 times 3" and the number 43 is that the former indicates the mathematical action of multiplying "4 times 3," which results in the value 12, while the latter simply represents the number itself.
To prove this, you can perform the mathematical operation of 4 x 3 = 12 and compare it to the number 43. As 12 is not equal to 43, it is clear that these are two different values.
In general, when we see a number with multiple digits, like 43, it is generally not thought of as the result of a mathematical operation. However, when we see an expression like 4 x 3, we know that it is the result of a multiplication operation and it is not just a number.

Answer:
m∠D = 109
Step-by-step explanation:
This is a parallelogram.
In parallelograms, the opposite interior angles are congruent, so we can write the following equation to find, first value x the measure of m∠D:
9x - 44 = 6x + 7
Transfer like terms to the same side of the equation.9x - 6x = 7 + 44
Add/subtract.3x = 51
Divide both sides by 3x = 17
Now we can calculate measure of m∠D:
m∠D = 9x - 44

Answer:
GCF = 8.
Step-by-step explanation:
First, we divide 264 by 224 and we get the identity:
264 = 1*224 + 40 ( That is 264 divided by 224 goes once and the remainder is 40)
Now we divide 224 by 40 to get:
224 = 5*40 + 24
Repeating this process, we get:
40 = 1*24 + 16
24 = 1*16 + 8
16 = 2*8 + 0 <------ we stop because the remainder is 0.
So, The GCF is 8.

The required domain of the vertical line is {5} and the range is all real numbers.
Given that,
Domain and range of the vertical line x = 5 is to be determined.
The domain is defined as the values of the independent variable for which there is a certain value of the dependent variable exists in the range of the function.
Here,
We can infer that the domain of this relation can only be constrained if a vertical line at x = 5 passes through 0 locations. This function's range can only be a collection of real numbers or a constraint.

Answer: 126 mm^2 - C
Step-by-step explanation: Hello! The formula for area of a triangle is 1/2(b)(h). b = base and h = height. You would multiply the base and height by 1/2 because a triangle is 1/2 the size of a square. The formula for the area of a square is (b)(h), and you would have to multiply (b)(h) to find the area of a triangle with the same base and height. The base of this triangle is 28 mm, and the height of this triangle is 9 mm. Substitute 28 mm in for the base, and 9 mm in for the height. (28)x(9) = 252. Now you have to multiply 252 x 1/2. 252 x 1/2 = 126. The answer is C, 126.

How to Write a Linear Function that Relates y to x of a Graph?The most common form of a linear function is y = mx + b, where m is the slope of the line and b is the y-intercept.
To write a linear function in this form, you will need to find the slope and y-intercept of the line.
The slope is the ratio of the change in y to the change in x, and the y-intercept is the point at which the line crosses the y-axis. Once you have these two values, you can substitute them into the equation and write the linear function.
