Since segment AC bisects (aka cuts in half) angle A, this means the two angles CAB and CAD are the same measure. I'll refer to this later as "fact 1".
Triangles ABC and ADC have the shared segment AC between them. By the reflexive property AC = AC. Any segment is equal in length to itself. I'll call this "fact 2" later on.
Similar to fact 1, we have angle ACB = angle ACD. This is because AC bisects angle BCD into two smaller equal halves. I'll call this fact 3
----------------------
To summarize so far, we have these three facts
angle CAB = angle CADAC = ACangle ACB = angle ACDin this exact order, we can use the ASA (angle side angle) congruence property to prove the two triangles are congruent. Facts 1 and 3 refer to the "A" parts of "ASA", while fact 2 refers to the "S" of "ASA". The order matters. Notice how the side is between the angles in question.
------------------------
Once we prove the triangles are congruent, we use CPCTC (corresponding parts of congruent triangles are congruent) to conclude that AB = AD and BC = BD. These pair of sides correspond, so they must be congruent in order for the entire triangles to be congruent overall.
It's like saying you had 2 identical houses, so the front doors must be the same. The houses are the triangles (the larger structure) and the door is an analogy to the sides (which are pieces of the larger structure).

A fair coin is tossed n times. For which value of n can the experimental probability of tossing tails equal the theoretical probability?
Answer:
The value of the coin tosses per time in the air
Step-by-step explanation:
The value of n for which the experimental probability of tossing tails can equal the theoretical probability is any even number.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
Example:
The probability of getting a head in tossing a coin.
P(H) = 1/2
We have,
The theoretical probability of tossing tails in a fair coin is 0.5 or 1/2.
The experimental probability of tossing tails in n trials is the number of times tails appear divided by n.
So, we want to find a value of n such that:
number of times tails appear / n = 0.5
Solving for n:
number of times tails appear = 0.5n
Since the number of times tails appear must be a whole number, n must be even.
This is because if n is odd, then it is not possible to have exactly half the trials result in tails.
For example,
If n=3, the possible numbers of tails that can appear are 0, 1, 2, or 3. Half of 3 is 1.5, which is not a whole number, so it is impossible to have exactly half the trials result in tails.
On the other hand,
If n=4, the possible numbers of tails that can appear are 0, 1, 2, 3, or 4.
Half of 4 is 2, which is a whole number, so it is possible to have exactly half the trials result in tails.
Therefore,
The value of n for which the experimental probability of tossing tails can equal the theoretical probability is any even number.

Step-by-step explanation:
Kevin is 3 years older than Daniel. Two years ago, Kevin was 4 times as old as
Daniel.
Let k be Kevin's age and let d be Daniel's age.
Which system of equations renresents this situation?
Answer:
k - 2 = 4d - 8
d + 1 = 4d - 8
Step-by-step explanation:
Daniel's age = d
Kevin's age = k
Given that, k = d + 3 -------------- (1)
Two years ago, the age of Daniel = d - 2
Two years ago, the age of Kevin = k - 2
Since, two years ago, Kevin was 4 times as old as
Daniel, k - 2 = 4(d - 2)
Opening the bracket,
k - 2 = 4d - 8
Since the value of k is d + 3 (see (1))
d + 3 - 2 = 4d - 8
d + 1 = 4d - 8
(I am just giving the answer cause I LOVE Linear Equation )
1 + 8 = 4d - d
9 = 3d
9/3 = d
3 = d
Therefore, Daniel's present age is 3 and Kevin's present age = 6

Work out the mean for the data set
below:
2.3, 0.3, 7,6.1, 9.7
Give your answer as a decimal.
Answer:
Mean = 5.08
Step-by-step explanation:
The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
[tex] \frac{2.3 + 0.3 + 7 + 6.1 + 9.7}{5} [/tex]

have completed 816 miles which is 46% of the trail. Can you find about how many miles for the total trip?
Answer:
1773.91 miles
Step-by-step explanation:
Given data
Completed miles= 816 miles
Percentage completion= 46%
Let the total distance be x
Hence
46% of x= 816
let us find x
46/100*x= 816
0.46x=816
x= 816/0.46
x= 1773.91
Therefore the total distance is 1773.91 miles

Consider the line y=8x - 3
Find the equation of the line that is parallel to this line and passes through the point (3, -2)
Find the equation of the line that is perpendicular to this line and passes through the point (3, -2)
Answer:
y=8x-26
y=-1/8x-13/8
Step-by-step explanation:
Y=kx+b
When the two lines are parallel,
k1=k2
k2=8 And passes through the point (3, -2)
So y+2=8(x-3)
Get the answer y=8x-26
When the two lines are perpendicular,
k1*k2=-1
K2=-1/8 And passes through the point (3,-2)
So y+2=-1/8（x-3）
Get the answer y=-1/8x-13/8
