angles of a different triangle, then the two triangles are comparable.
Similarity hypothesis, angle, and AA
Given that: The interior product of the AA similarity hypothesis
The angle sum property of a triangle states that the angles of a triangle are 180°,
Consequently, the third angle is also congruent when two angles are
congruent

On the y-axis, this value c is referred to as the intercept. Y = mx + c represents the equation of a straight line with gradient m and intercept c on the y-axis".
What is equation?A mathematical statement known as an equation is made up of two expressions joined together by the equal sign. A formula would be 3x - 5 = 16, for instance. When this equation is solved, we discover that the value of the variable x is 7. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. The point-slope form, standard form, and slope-intercept form are the three main types of linear equations.

there is a linear relationship between the distance that a car drives and the amount of gas left in the tank of the car. the value of r2 for this linear relationship is 98.01%. what is the value of r?
A linear relationship between the distance that a car drives and the amount of gas left in the tank of the car is negative, and the value of r is -0.99
A linear relationship between the distance that a car drives and the amount of gas left in the tank of the car are negative because when a car travels a distance, it consumes fuel, and so fuel decrease with distance
Calculating the value of r
Given, r^2=98.01%
r^2=0.9801
r=±√0.9801
r=±0.99
Since r should be negative, so we pick the negative value and reject the positive value

Outward journey Speed = 20 km/hr , James stopped for 45 Mins ,Average speed homewars 15 km/hr
What is speed, for instance?
A measure of speed is the rate at which something is happening, moving, or moving swiftly. The speed of a car being driven at 45 mph serves as an illustration. A person cleaning a room in 10 minutes is an illustration of speed.From graph Journey Started at 2PM
on 3PM James covered 20 km
Hence Speed = (20 - 0)/(3 -2) = 20 km/hr
outward journey Speed = 20 km/hr
Now outward Distance = 45 km
Time taken = 45/20 = 2 hr 15 min
Hence reached at 4 : 15 PM

What is the equation of the line that passes through the point (5, 3) and has an
undefined slope?
The equation of the line will be expressed as x = 5.
Slope of a line may be defined as the steepness of a curve plotted on paper. The slope of a line between two points (x₁, y₁) and (x₂, y₂) can be calculated by formula m = (y₂ - y₁)/(x₂ - x₁).
If we have two points and we have to find equation of line through two points (x₁, y₁) then equation will be (y - y₁) = m(x - x₁) where m is the slope of line.
We have two points (5, 3) and slope is undefined.
Undefined slope can be expressed as 1/0. So, the equation of line through (5, 3) will be
(y - 3) = 1/0 (x - 5)
=> x - 5 =0
=> x = 5
This is the equation of line, and this line will be parallel to y-axis.

⇒The side with magnitude 12 in the bigger triangle is proportional with the side with magnitude 4 in the smaller triangle
⇒The side with magnitude 6 in the bigger triangle is proportional with the side with magnitude x in the smaller triangle. The proportionality theorem allows us to equalize the proportions of the sides

Jennifer has a collection of weights that each weigh 4, 6, or 9 pounds. If altogether, the weights weigh 42 pounds, what is the largest number of weights Jennifer could own?
The largest number of weights Jennifer could own is 798.
When do we use multiplication?Repeated addition of the same number is made easier by multiplying the numbers. When we need to merge groups of similar sizes, we employ it. For instance, if there are 5 baskets, each containing 4 apples, we can use multiplication to get the total number of apples, which is 5 x 4 = 20 apples.
We can rapidly determine the total number of things by multiplying. When multiplying, we'll consider the number of groups with similar sizes and the number of items in each group.
Given: The collection of weights : 4 , 6 and 9 pounds
The total weight of the weights = 42 pounds
Thus the largest number of weights jennifer could own is 4+6+9 = 19 multiplied by the total weight of the weights
= 19 × 42

Similarity Theorems
Triangles ABG and DCB are similar by the AA similarity postulate
"If two angles in one triangle are congruent to two angles in another triangle, then the two triangles are similar"
The steps previous to statement 7 prove angles C and B are congruent because they are formed by two parallel lines that intersect a common line.
On the other side, angles DBC and AGB are congruent also because they are both right angles.
With two corresponding congruent angles, the AA similarity postulate is satisfied and the triangles are similar.

The slope of the line is represented by the word m which is obtained as 0.5.
What is the slope?The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
To determine a line's inclination or steepness, use the slope formula. Calculating the ratio of the change in the y-axis to the change in the x-axis may be used to calculate the slope of any line.
From the graph, the data is observed as,
(x₁,y₁)=(0,1)
(x₂,y₂) = (-2,0)
The slope of the line is found as,
[tex]\rm m =\dfrac{0-1}{-2-0} \\\\ m = 0.5[/tex]
