Using PEMDAS to resolve the trigonometric identity which involves trigonometric function, the value of tan A + tan B is 416 / 87

What is Trigonometric Identity

A trigonometric identity is an equation that is true for any value of the variables involved. These identities are useful in solving problems involving trigonometric functions. Examples include the Pythagorean identity, the sine and cosine addition formulas, and the double angle formulas.

In the given problem, we have a compound angle problem and we can solve it as;

tan A + tan B = [(tan A + tan B)] / [1 - tan A * tan B]

tan A = 7/24tan B = 15 / 8

Substituting the values into the expression and solve;

tan A + tan B = [(7/24 + 15/8)] /[1 - (7/24)(15/8)]

Applying the rules of PEMDAS;

tan A + tan B = (13 / 6) / (29 / 64)

tan A + tan B = 416/87

Find the trigonometric ratios for both acute angles in fraction and decimal form to the nearest ten-thousandths when appropriate.

Answers

The trigonometric functions are sin A = 12/13, sin B = 5/13, cos A = 5/13, cos B = 12/13, tan A = 12/5, and tan B = 5/12 as fractions.

What are Trigonometric functions?

Trigonometric functions are defined as the functions which show the relationship between the angle and sides of a right-angled triangle.

The trigonometric functions are given in the question

Apply the sine ratio on the given right triangle

⇒ sin(θ) = Perpendicular/hypotenuse

sin A = BC/AB

sin A = 12/13

sin B = AC/AB

sin B = 5/13

Apply the cosine ratio on the given right triangle

⇒ cos(θ) = Base/hypotenuse

cos A = AC/AB

cos A = 5/13

cos B = BC/AB

cos B = 12/13

Apply the tangent ratio on the given right triangle

⇒ sin(θ) = Perpendicular/Base

tan A = BC/AC

tan A = 12/5

A line passes through the point (-10,1) and has a slope of 3/2. Write an equation in point-slope form for this line.

Answers

The line passes through the point (-10,1) and has a slope of 3/20 has the equation as: y - 1 = 3/2 (x + 10)

How to write the equation of the line

The general form of a linear equation is y - y₁ = m (x - x₁).

It draws attention to the line's slope and one of the line's points (that is not the y-intercept)

The point slope formula is given by y - y₁ = m (x - x₁), where:

y = output value

y₁= the given y coordinate point

m = slope

x = input value

x₁ = the given x coordinate

substituting the point (-10,1) and slope 3/2

y - y₁ = m (x - x₁)

y - 1 = 3/2 (x + 10)

The answer is the intercept point of both lines, so we need to find the point when both the line touches, with out graphing we can see by the table that point (2, -2) intercepts with the line on the graph.

hope this helps :)

Answer:

C) (2, -2)

--------------------------

From the table we see each y-coordinate is the negative of the corresponding x-coordinate. It gives us the second line:

y = - x

The first line is given y = 1/2x - 3, equate both to get:

- x = 1/2x - 3-2x = x - 6x + 2x = 63x = 6x = 2

Then the value of y:

y = - x = - 2

The solution is (2, - 2).

Answers

The wheel is spinning at 23.80 miles per hour

How determine how fast the wheel spinning in miles per hour?

The wheel speed in miles per hour can be calculated using the expression below:

Speed in miles per hour = Wheels RPM × 2 × π × r × (60 / 63360),

where r is the radius of wheel , 60 converts minute to hour and 63360

converts inches to miles

Speed in miles per hour = 800 × 2 × π × 5 × (60 / 63360)

Speed in miles per hour = 23.80 miles per hour

Thus, the wheel spins at 23.80 miles per hour

What is Triangle?

Triangle is a closed polygon consisting of three sides, three vertices and three angles.

Similar triangles are those triangle for which the ratio of corresponding sides is same without affecting the shape.

Given that ΔABC and ΔPQR are similar.

Let x be the side length of PR.

Ratio of their side lengths are equal.

AB : PQ = BC : QR = AC : PR

5 : 45 = 8 : 72 = 6 : x

Take the ratios 8 : 72 = 6 : x

⇒ 8 / 72 = 6 / x

Cross multiplying,

⇒ 8x = 72 × 6

⇒ 8x = 432

⇒ x = 432 / 8 = 54

Hence the side length missing is 54 units.

In the United states, the federal government has led anti-smoking campaigns for more than 40 years. But according to a new report from the U.S. Surgeon General, the nation's top health official, progress in preventing American teenagers and young adults from using tobacco has stalled.The report is a tome - nearly 900 pages long. Its focus is on how to prevent tobacco use among teenagers and young adults.Smoking Among Teens UpWhile the overall rate of tobacco use has drastically declined since the first surgeon general's report more than 40 years ago, this report shows that children as young as 10 are developing a deadly tobacco addiction. Surgeon General Regina Benjamin says the statistics are shocking. "Every day 1,200 Americans die from smoking. And each of those people are being replaced by two young smokers," she stated. The goal is to end tobacco use among teens and young adults. Studies show that teenagers are much more vulnerable than adults to the addictive properties of nicotine, a drug found naturally in tobacco. And that tobacco use interferes with lung development.More than 90 percent of adult smokers lit up their first cigarette before they turned 18. Many start the habit when they are in middle school, between 11 and 13 years old. "Today, more than 600,000 middle school students smoke, and three million high school students smoke cigarettes," Benjamin explained.Studies also show that more than one in three young adults between the ages of 16 and 26 smoke. On the other hand, fewer than one percent of smokers start after the age of 26. Anti-Smoking Campaign for YouthDr. Benjamin outlined plans to launch a media campaign like this one aimed at youth. "I want our next generation to be tobacco-free," she said. "That's the goal, to have our next generation tobacco free."Dr. Benjamin wants to involve parents and teachers and to refocus on community anti-smoking programs, including programs in schools.Ads Targeting Teens, Tobacco Mimic CandyThe report criticizes tobacco companies for advertising campaigns that target young people and for making products like tobacco candy.It cites the effectiveness of placing higher sales taxes on tobacco products, which make them too costly for most teens to buy.A U.S. Health Department spokesman said helping young people avoid tobacco addiction will cut the number of tobacco-related illnesses and premature deaths and spare more families the devastating emotional toll.What does the word tome (second paragraph) mean, based on the context?1 a newspaper article2 an encyclopedia volume3 an epic poem4 a short story5 a lengthy book Part BRemember that GDP stands for gross domestic product.
