To prove both triangle similar ratio of their sides must be equal
AC/GI = BC/HI
Therefore last option is correct .
What is difference between congruency and similarity ?The difference between congruence and similarity can be examined mathematically. These two words are defined by shape, proportion, and angle.
Congruent shapes have the same dimensions and overlap when stacked. Two congruent objects have the same size and shape, but different orientations and placements in space. This doesn't change the fact that they are the same as they have the same physical properties, angles and dimensions.
Similarity means similar but not identical. A shape can be mathematically equivalent in its base form as follows: B. Circles, but different sizes.

Explain how you can find the y-intercept of a function when given an equation of a graph.
The y-intercept of a function is the value of y when x = 0, which is represented as the value of b in the slope-intercept equation y = mx + b. b is the y-intercept.
What is the Y-intercept of a Function?If an equation of graph that represents a function is given in slope-intercept form as y = mx + b, the value of b in the function is the value of the y-intercept of the y-intercept.
The y-intercept of the function is the same as the value of y when the value of x is 0, or the point where the line of the function intercepts the y-axis on a given graph that represents the function.
For example, if we are given the equation of a graph that represents a function as, y = 3x + 4, the y-intercept of the function would be 4.
In summary, the y-intercept of the function is the value of b in the equation of the function that is expressed as y = mx + b in slope-intercept form.

What is an equation?
An equation is a mathematical statement that proves two mathematical expressions are equal in algebra, and this is how it is most commonly used. In the equation 3x + 5 = 14, for instance, the two expressions 3x + 5 and 14 are separated.
Equation:
2((2/5) x+8)=4(14-(1/5)x)
1. The division property of equality states that if both sides of an equation are divided by a common real number that is not equal to 0, the quotients remain equal .
2((2/5) x+8)/2=4(14-(1/5)x)/2
(2/5) x+8=2(14-(1/5)x)
2. multiplying a quantity by the sum of two or more terms is the same as adding together the products of the original quantity and each term
(2/5) x+8=28-(2/5) x
3. when the same quantity is added to both sides of an equation, it produces an equivalent equation
(2/5) x +(2/5) x+8=(2/5) x+28-(2/5) x = 28
4. The Subtraction Property of Equality states that an equal value subtracted or removed from two equal items will result in a new equal amount
(4x)/5+8-8=28-8=20
5. The multiplication property of equality states that when we multiply both sides of an equation by the same number, the two sides remain equal.
*5(4x)/5= 20*5
4x=100
6. The division property of equality states that if both sides of an equation are divided by a common real number that is not equal to 0, the quotients remain equal .

Standard form of line that passes through (6.-1) and it parallel to the line represented by 8x + 3Y= 15
The standard form equation for a line passing through the point (6, -1) and parallel to the line denoted by 8x + 3y = 15 is 8x + 3y = 45.
The standard form equation
ax + by = c
Here a, b, and c are constants and therefore use the slope-intercept form.
y = mx + c .... (1)
where m is the slope, b = y-intercept
8x + 3y = 15
3y = -8x + 15
y = -8 / 3 x + 5
Slope (m) = - 8 / 3
It passes through a line that has points (6, -1)
Let's find b by putting the value of m = - 8/3, x = 6, and y = -1 in equation (1).
-1 = - 8 / 3 (6) + c
-1 = -48 / 3 + c
-1 = -16 + c
c = -1 + 16
c = 15
Therefore,
y = - 8 / 3 x + 15
8 / 3 x + y = 15
=> 8x + 3y = 45
8x + 3y = 45 is the standard form of the line that passes through (6,-1) and is parallel to the line represented by 8x + 3y= 15.

Find the x-intercept and y-intercept of the line???
The x-intercept of the line is x = -2,and the y-intercept of the line is y = -6.
Determining the x-intercept and the y-intercept of a lineFrom the question, we are to determine the x-intercept and y-intercept of the line.
The x-intercept of a line is the point where y = 0
and
The y-intercept of a line is the point where x = 0
The equation for the line is
6x + 2y = -12
To determine the x-intercept, substitute y = 0 in the equation
6x + 2y = -12
6x + 2(0) = -12
6x + 0 = -12
6x = -12
Divide both sides by 6
6x/6 = -12/6
x = -2
Hence, the x-intercept is x = -2
To determine the y-intercept, substitute x = 0 in the equation
6x + 2y = -12
6(0) + 2y = -12
0 + 2y = -12
2y = -12
Divide both sides by 2
2y/2 = -12/2
y = -6
Hence, the y-intercept is y = -6

An experiment consists of rolling a fair die (sides numbered 1, 2, 3, 4, 5, 6) and then tossing a coin (with faces Heads and Tails).
Let A be the event that the number rolled is a 3 or a 4.
Let B be the event that a heads is flipped.
Are events A and B independent? Why or why not?
The events A and B are independent events
How to determine the type of the event?The sections on the dice are given as
S = {1, 2, 3, 4, 5, 6}
These sections mean that:
n(3) = 1 and n(4) = 1
Recall that:
A be the event that the number rolled is a 3 or a 4.
So, we have
P(A) = P(3) + P(4)
This gives
P(A) = 1/6 + 1/6 = 1/3
Also, we have
Coin = {Head, Tail}
Where
B be the event that a head is flipped.
This means that
P(B) = 1/2
The occurrence of an event in event A does not hinder the occurrence of another occurrence in event B
This means that the events are independent event
i.e. they do not depend on each other

cos75°cos15° + sin75°sin15°
Using the relation Cos (θ) = Sin( 90° - θ)
Sin (θ) = cos (90° - θ)
Sin ( 2θ) = 2 sin θ cos θ

A line has a slope of
-(6/5)
(a) What is the slope of the line parallel to it?
(b) What is the slope of the line perpendicular to it?
a) What is the slope of the line parallel to it?
Parallel lines will never intersect, meaning they have equivalent slopes, so the answer to this part is -(6/5).
b) What is the slope of the line perpendicular to it?
Perpendicular lines will intersect, creating a 90-degree angle, meaning all values in the graphs have been flipped. Thus, the slope of any perpendicular line is the negative reciprocal of the given slope (-1/x). The negative reciprocal of -(6/5) is 5/6, so that is the answer.
