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

A bag has 8 red marbles, 4 green marbles, and 2 yellow marbles. Bill draws a red marble from the bag and does not replace it. What is the probability of Bill drawing a yellow marble next? A. 1/7 B. 1/13 C. 2/13 D. 1/14
Answer:
c. 2/13
Step-by-step explanation:
The bag starts with 8 red marbles, 4 green marbles, and 2 yellow marbles. Since he draws a red marble from the bag and does not replace it, there will be one less marble.
So now there are 7 red marbles, 4 green marbles, and 2 yellow marbles. Add the number of marbles together and then find the probability of drawing a yellow marble.
7+4+2 = 13
2/13
So the probability of Bill drawing a yellow marble would be 2/13.

At a restaurant, the ratio of cheeseburgers ordered to hamburgers ordered is 5:3. If 60 hamburgers are ordered, how many cheeseburgers are ordered?
Answer:
20
Step-by-step explanation:
3x = 60
x = 20
--> 5*20 = 100 cheeseburgers
Answer:
100
Step-by-step explanation:
Ratio of cheeseburgers to hamburgers is 5:3
If we let C be the number of cheeseburgers and H the number of hamburgers we can write this as
C:H = 5:3
or
C/H = 5/3
Multiply both sides by H
==> C = (5/3)H
Given H =- 60, number of cheeseburgers, C = (5/3) x 60 = 100

Enter your answer in the box.
Answer:
1872 ft.²
Step-by-step explanation:
First lets figure out all of the easy shapes:
The bottom one: 8 * 7 = 56
The one on the left: 5 * 8 = 40
The one of top: 8 * 3 = 24
The slanted rectangle: 5 * 8 = 40
The small rectangle below that : 2 * 8 = 16
Now we just have the polygon facing toward us. It can be broken up into 2 parts:
The lower half: 2 * 7 = 14
Imagine a line going from the top of the line marked "2" straight across to the other side. That is the bottom half. Now we are left with a trapezoid. The formula for the area of a trapezoid is as follows:
A = ((a + b) / 2) * h
What this means is that we had the top and bottom of the figure, divide that by 2, and multiply it by the height. That can be shown here:
(3 + 7) / 2 = 5 * 3 = 15
15 is the area of the trapezoid. Now we can combine that with 14 to get the total area of the polygon:
14 + 15 = 29
Then do the same again for the other identical figure
14 + 15 = 29
Now we have all the areas of our shapes. Let's add them up:
56 + 40 + 24 + 40 + 16 + 29 + 29 = 234
234 is the total surface area of the box. Since there are 8 boxes, multiply this by 8 to get your final answer:
234 * 8 = 1872 ft.²
Don't forget to include units!
The solution is : 1872 ft.² of the new material is needed to build all 8 containers.
What is area ?Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.

Then do the same again for the other identical figure
14 + 15 = 29
Now we have all the areas of our shapes. Let's add them up:
56 + 40 + 24 + 40 + 16 + 29 + 29 = 234
234 is the total surface area of the box.
Since there are 8 boxes, multiply this by 8 to get your final answer:
234 * 8 = 1872 ft.²

C^2 goes in the first box because it’s the only missing variable from the ones given.
Then c^2 goes in the second box because it hasn’t been changed.
Then 2 goes in the third box because (1/2ab x 4 = 4/2 ab = 2ab)
Then c^2 goes in the last box because it hasn’t been changed either, plus it completes the Pythagorean formula (a^2 + b^2 = c^2) so it seems the most logical

x=30
Hope it helps!
Mark as brainliest please!
Answer:
21/35 = 18/30x = 30Step-by-step explanation:
Given proportion,
→ 21/35 = 18/x
Now we have to,
→ Find the required value of x.
Let's find the value of x,
→ 21/35 = 18/x
→ 21x = 18 × 35
→ 21x = 630
→ x = 630/21
→ [ x = 30 ]
Hence, the value of x is 30.

Some students recorded how many minutes they spent on the phone in one day. They put the results in a Stem-and-Leaf Plot.
What is the mean number of minutes spent on the phone?
Explanation:
The data from the stem-and-leaf plot is:
10,
24,25,26,
30,30,32,33,
40,45,46
Add up those values
10+24+25+26+30+30+32+33+40+45+46 = 341
Then divide over n = 11 which is the sample size.
341/11 = 31 is the arithmetic mean.
Answer:
341/11 = 31 is the arithmetic mean.
