Explain the cosine rule and sine rule while also saying how to use it and provide examples (keep it in simple terms)

Answers

Answer:

Sure, I'll explain the cosine rule and sine rule in simple terms:

The cosine rule (also known as the law of cosines) is used to find the length of a side or the measure of an angle in a triangle given the lengths of the other sides and the angle between those sides. It states that c^2 = a^2 + b^2 - 2ab cos(C), where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.

Here's an example of how to use the cosine

Suppose we have a triangle with sides a=6, b=8, and an angle between them c=45 degrees. We want to find the length of the remaining side of the triangle, side a.

Using the cosine rule:

a^2 = b^2 + c^2 - 2bc * cosA

where A is the angle opposite side a, we can plug in our values and solve for a:

a^2 = 8^2 + 6^2 - 2(8)(6) * cos(45)

a^2 = 64 + 36 - 96 * 0.707

a^2 = 10.56

a = sqrt(10.56)

a = 3.25 (rounded to two decimal places)

Therefore, the length of side a is approximately 3.25 units.

Step-by-step explanation:

The Answer is U=8,5 V=7,5 W=6,10

Write the coordinates of the vertices after a rotation 180° counterclockwise around the origin.

Answers

Answer: swap u and v I don't think w will change

Step-by-step explanation:

-

Well if it’s going 180 degrees, then it’s gonna be in Q1. Therefore the numbers would be in the positive, positive section. So U -8 = U’ +8, V = V’ +6 and W = W’ +6. That goes to show that 180 degrees will have the same coordinates.

∠A and ∠B are supplementary angles. If m∠A = (3x+1)∘ and m∠B = (x-9)∘, then find the measure of ∠B.

Answers

Answer:

X= 45

Step-by-step explanation:

So you do

3x+1+x-9=180

Because  supplementary angles are 180°

Then

3x+x = 4x

1 - 9 = -10

4x-10=180

4x-10+(10)=180+(10)

4x=190  

x=45

Domingo and Bethany drove along the same highway, in opposite directions. Domingo left at 1 p.m., traveling westbound at 55 mph. Bethany left at the same time, traveling eastbound at 60 mph. Domingo and Bethany were 575 miles apart when they started driving. At what time did they pass each other?

Answers

Step-by-step explanation:

Let's first figure out how far each of them traveled before they meet. Let TIME be the time in hours since they began traveling.

Domingo traveled a distance of 55 * TIME miles

Bethany traveled a distance of 60 * TIME miles

We know that their total distance is 575 miles. So we can write the equation:

55 * TIME + 60 * TIME = 575

Simplifying this equation, we get:

115 * TIME = 575

Dividing both sides by 115, we get:

TIME = 5

So they meet 5 hours after they began traveling. Since Domingo left at 1 p.m., he will meet Bethany at 6 p.m.

They will pass each other at 6 pm.

Given,

Domingo and Bethany drove along the same highway but in opposite direction.

Let's first figure out how far each of them traveled before they meet.

Let x be the time in hours since they began traveling.

Domingo traveled a distance of 55 * x miles

Bethany traveled a distance of 60 * x miles

We know that their total distance is 575 miles. So we can write the equation as,

55 * x + 60 * x = 575

Further simplifying this equation, we get:

115 * x = 575

x = 5

So they meet 5 hours after they began traveling.

Since Domingo left at 1 p.m., he will meet Bethany at 6 p.m.

What’s j+12=25 tape diagram

Answers

well you would take 25 and take 12 away. like this: 25-12=? so 25-12 would be 13. therefore j=13!
What is an Equation?

An equation is a mathematical statement that shows two mathematical expressions equal.

An equation consists a variable that does not have a fixed value to it.


Given,

j+12=25

Here ‘j’ is the variable.

To find ‘j’ we just need to 12 from 25.

So, 25 - 12 = 13

Hence, now we know that ‘j’ is equal to 13.


Proof :

13 + 12 = 25

Write an equation that Noah can use to find if he knows .

Answers

Answer:  x = T - 4

T = y + 5

Step-by-step explanation:

a. To find the number of liters of soda water (x) if Noah knows the total number of liters (T) of sparkling orange juice he needs to prepare, the equation can be written as:

x = T - 4

b. To find the number of liters of sparkling orange juice (T) Noah can make if the school purchases a certain number of liters of orange juice (y), the equation can be written as:

T = y + 5

In both equations, x represents the number of liters of soda water, T represents the total number of liters of sparkling orange juice, and y represents the number of liters of orange juice.
