The statement that "If two adjacent angles form a right angle, then the angles are complementary", is true
How to determine the truth value of the conditional?The conditional is given as:
If two adjacent angles form a right angle, then the angles are complementary
As a general rule, complementary angles add up to 90 degrees i.e. right angle
This means that adjacent angles that add up to 90 degrees are complementary angles
Hence, the statement that "If two adjacent angles form a right angle, then the angles are complementary", is true

Two strait lengths of wire are placed on the ground forming vertical angles. if the mesure of one of the angles formed is 72 what are the other three angles
The other three angles are 72° , 108° and 108°.
Two strait lengths of wire are placed on the ground forming vertical angles. The measure of one of the angles formed is 72° . We know that sum of all four angles will be 360°. We also know that the vertical angles are congruent. If the measure of one angle out of four angles is 72° and straight lines equal 180°. So, we need to subtract 72° from 180°.
180° - 72° = 108°
The other angle will be 108°. As the vertical angles are equal, so the four angles will be 72° , 72° , 108° and 108°.
The other three angles are 72° , 108° and 108°.

What is Population Density?The amount of people in a given region per unit area is known as population density.
In 2018, Singapore had a population density of 21,400 people per square mile.
The parameters provided are
There are 21400 inhabitants in total.
Area = 1 square mile,
The square kilometer to square mile conversion
1 x 1.609² = 2.588881 Km²
Residents per square mile divided by the population
21400 x 2.588881 is the population density.
8266.12 people are found in every square kilometer.
As a result, Singapore has a population density of 8266.12 persons per square kilometer.

a game where two players each throw two dice each. if any one die matches the other, you win a dollar. if there is no match, you lose a dollar. would you play this game or not and why?
Final answer:
I would play the game because we could win with probability 17/27.
What significance does probability have ?Information about the possibility that something will happen is provided by probability. For instance, meteorologists use weather patterns to forecast the likelihood of rain. Probability theory is utilized in epidemiology to comprehend the connection between exposures and the risk of health outcomes.
According to the First Law of Probability, the outcomes of one chance event have no bearing on those of succeeding chances occurrences. Consequently, the chance of getting heads the second time you flip it remains at 1 in 2. The chances of getting heads on the sixth flip, even if you got five consecutive heads, stay at 12.
Everyday existence heavily relies on probability. Weather predictions, sports and gaming tactics, insurance purchases or sales, internet shopping, and online gaming.
Explanation:
If both of your dice, or at least one of them, match at least one of the other player's dice, you win. This provides us five scenarios where we win. Let's use the letters A, B, C, and D to represent the results of the dice, with your dice being A and B and the other player's being C and D. The five possibilities are:
1) [tex]A = B[/tex]
2) [tex]A = C[/tex]
3) [tex]A = D[/tex]
4) [tex]B = C[/tex]
5) [tex]B = D[/tex]
A B C D
1) [tex]6 * 1 * 6 * 6[/tex] A can be anything, B has 1 option, C and D can be anything.
2) [tex]6 * 5 * 1 * 6[/tex] A can be anything, C has 1 option, A != B so B has 5 options.
3) [tex]6 * 5 * 5 * 1[/tex] A can be anything, D has 1 option, A !=B and A != C so B and C have 5 options.
4) [tex]5 * 6 * 1 * 5[/tex] B can be anything, C has 1 option, A != B and A != D so B and D have 5 options.
5) [tex]5 * 6 * 4 * 1[/tex] B can be anything, D has 1 option, A != B so A has 5 options, C != A and C != B so it has 4 options.
Therefore, it becomes [tex](6^3 + 6^2*5 + 2*6*5^2 + 6*5*4) / 6^4[/tex]

Using complementary angles, the measure of angle 4 is of 39º.
What are complementary angles?If two angles A and B are complementary, the sum of their measures is of 90º.
In this problem, angles 3 and 4 are complementary, hence:
m<3 + m<4 = 90º.
Angles 1 and 3 are opposite by the same vertex, hence they are congruent and we can find x as follows:
m<1 = m<3
4x - 13 = 2x + 19.
2x = 32
x = 16.
The measure of angle 3 is given by:
m<3 = 2(16) + 19 = 51.
Hence the measure of angle 4 is found as follows:
m<3 + m<4 = 90º.
51 + m<4 = 90º.
m<4 = 39º.

The dimensions of rectangle B are 4.5 inches by 3 inches. So the correct option is the first one.
What are the possible dimensions of rectangle B?
We know that the dimensions of rectangle A are 6cm by 4cm, and rectangle B is similar to rectangle A, then the two rectangles have the same shape but different size.
Notice that the ratio between the dimensions of rectangle A is:
R = 6/4 = 3/2 = 1.5
Then, any other rectangle with the same ratio will be similar to rectangle A.
If we take the ratios for the options we get:
1) 4.5 in by 3 in:
R = 4.5/3 = 1.5
So yes, this rectangle is similar to rectangle A, then these can be the dimensions of rectangle B.
Then we conclude that the dimensions of rectangle B are 4.5 inches by 3 inches, and thus, the correct option is the first one.

Write a recursive function called digit_count() that takes a positive integer as a parameter and returns the number of digits in the integer.
The count of integers is returned to the main function at the end of the function.
What are recursive functions?A recursive function is one that calls itself while running. The process may be repeated several times, with the result and the end of each iteration output. The function Count() below employs recursion to count from 1 to 10 using any number between 1 and 9.So,
The Python recursive function DigitCount(), which uses comments to explain each line, is as follows:
#This defines the function
def countdigits(n):
#If the integer is less than 10
if n< 10:
#Then the integer has 1 digit
return 1
#Otherwise,
else:
#Count the number of integers
return 1 + countDigits(n / 10)
At the end of the function, the count of integers is returned to the main function.
Therefore, the count of integers is returned to the main function at the end of the function.
