When two angles are vertical angles, then they are congruent, the hypothesis of the conditional is that D. Two angles are vertical angles.
What is vertical angles?When two lines cross at a point, vertical angles are created. They are always on an equal footing. In other words, four angles are created anytime two lines cross or intersect. It is evident that two opposed angles are equal and are referred to as vertical angles.
It should be noted that if p and q are statements, the conditional of q by p is “if p then q” denoted p → q. We call p the hypothesis of the conditional and q the conclusion.
Therefore, if two angles are vertical angles, then they are congruent, the hypothesis of the conditional is that the two angles are vertical angles.

An airplane leaves Los Angeles and travels 5 hours to New York City. The return trip travels along the same route and takes 6 hours and 15 minutes because the plane travels 99 miles per hour slower due to a headwind. Find the distance that the plane flies between the two cities. The distance that the plane flies between the two cities is ____ miles.
Use the equation distance=rate*time
The distance that the plane flies between the two cities is 2475 miles.
What is velocity?Velocity is the rate of distance covered per time. Velocity could be average or instantaneous.
For example, if a car drives 50 meters for 10 seconds and it is constant then 50/10 = 5 meters/second will be the velocity.
Time taken = distance covered / velocity
In the first case ;
Time taken = 5 hour.
Velocity = V(Let's say)
Distance covered = x
So,
5 = x/V
x = 5V
Now,
In the second case ;
Velocity = V - 99 (99 slower to first)
Time taken = 6 hours and 15 minutes = 6.25 hour
Distance covered = x
So,
6.25 = x/(V - 99)
x = 6.25V - 618.75
By equating
6.25V - 618.75 = 5V
1.25V = 618.75
V = 495 miles / hour
Now,
x = 5(495) = 2475 miles.
Hence "The distance that the plane flies between the two cities is 2475 miles".

11. You have just been hired as advertising manager of The Daily Chronicle, a not-very- successful newspaper. In the past, The Chronicle contained one-half advertising and one-half news stories. Current industry research indicates a newspaper must have three times as much advertising as news stories to make money. In addition, the advertising must be divided in the following ratio: 5 to 3 to 1, retail advertising to national advertising to classified advertising. The Chronicle is typically 48 pages in length. 1 a) How many pages should be advertising, and how many should be news stories? b) Based on the industry ratios, how should the pages be divided among the three types of advertising? c) After you made the changes in the advertising distributions ratios, your newspaper began making a profit—for the first time in years. If last year’s total advertising revenue was $810,000, how much was earned by each type of advertising? d) When you accepted the job of advertising manager, in addition to your salary, you were promised a 1/50 share of each year’s revenue from retail and classified advertising and a 1/75 share for national. What bonus will you receive for last year’s sales?
Using proportions, it is found that:
a) 36 pages should be of advertising and 12 pages should be of news stories.
b) 20 pages should be of retail advertising, 12 pages should be of national advertising and 4 pages should be of classified advertising.
c) $450,000 was earned by retail advertising, $270,000 was earned by national advertising and $90,000 was earned by classified advertising.
d) You will receive a bonus of $14,400 for last year's sales.
What is a proportion and what is an example of application?A proportion is a fraction of a total amount, and equations can be built to find the measures using a rule of three, that can be either direct or inverse, deriving from proportional relationships.
One example of application is for ratio problems, as fractions of the total amount are built from the ratios, as given in this problem.
For item a, we have that three times as much advertising as news stories are needed, hence 3/4 of the 48 pages are advertising, hence:
3/4 x 48 = 0.75 x 48 = 36.
Hence:
The remaining 12 are of news stories.
For item b, from the ratio of 5 to 3 to 1, we have that:
5/9 of the advertising pages should be of retail advertising.3/9 of the advertising pages should be of national advertising.1/9 of the advertising pages should be of classified advertising.Hence:
5/9 x 36 = 20 pages. -> Retail.3/9 x 36 = 12 pages. -> National.1/9 x 36 = 4 pages. -> ClassifiedIn item c, from the same ratio as above, the advertising values are found as follows:
5/9 x 810,000 = $450,000. -> Retail.3/9 x 810,000 = $270,000. -> National.1/9 x 810,000 = $90,000. -> ClassifiedFor item d, the bonus is calculated as follows:
1/50(450,000 + 90,000) + 1/75(270,000) = $14,400.

Given that,
In a picture we have a triangle with 3 sides.
sides are a,8 and 2.
by using Pythagorean theorem
The Pythagorean Theorem, generally referred to as Pythagoras' Theorem, is a basic relationship between a right triangle's three sides. The Pythagorean theorem states that, given a right triangle, which is a triangle in which one of the angles is 90 degrees, the hypotenuse, the right triangle's longest side, forms a square whose area is equal to the sum of the areas of its other two sides.
In other words, given that the triangle's longest side, c, is also its hypotenuse and that sides a and b are its other two sides:
a² + b² = c²
a²+(2)²=8²
a²+4=64
a²=64-4
a²=60
Take root on both sides
[tex]\sqrt{a^{2} } =\sqrt{60}[/tex]
a=2[tex]\sqrt{15}[/tex]
