FINDING "B" in a TRIANGLE

I volunteered to make the scribe for "FINDING B". Our lesson in math now makes me so interested about it. Honestly, for the first time, I understood our lesson and I was amazed that I was'nt struggling anymore!!! I really payed attention to it because I really wanted to learn. And now, here I'am scribing and sharing all the things that I know to find the "B" in a triangle.

To be able to find the "B", you MUST know the FORMULA first:

After knowing the formula, you now have to FIND the "B". Look at the triangle below. It shows that "B" is ?.

*Please get a piece of looseleaf. Try to find the "B" in the picture given below.

Good job for you if you did it right!!! But if you don't, its alright, just try your best next time. Here is the proper way of substituting. You may copy if you wish.

So, that means that "B" is equals to 17.3 cm.

Thank you for participating and hopefully that you learned something. Also, thank you very much for this opportunity.

How to find "A" in a Right Triangle =)

Yesterday (05.09) and today (05.10), we learned "Finding A,B, and C in a Right Triangle"


I am assigned to scribe about "Finding A." Follow along with this steps:

1.) For you to be able to find the missing side which is A, you must know the formula first:


2.) To begin with, you must know what the given numbers are:

Now you know that:
(Hypotenuse) C = 10
(Base) B = 6
(Altitude) A = ?

3.) Once you've gathered information, we begin to substitute:

Hope this helped you though it's short. It's really easy! But you MUST ALWAYS know what the formulas are for you to be able to substitute all the way to the answer. Refer to your foldable paper, it's a good source for reviews!

How to find "A" in a Right Triangle by Andrea Tria, 817 =)

Boeun's Scribe Post 04/17/07

Today in class (day 6 - period 6),
we corrected our blue sheets and got our homework. (blue sheet).

What we corrected (blue sheet):
LEGO
TRIANGLES (OR DIAMONDS)
I AM AN UPSIDE DOWN L

I'm explaining the LEGO one.

1. Draw out the next two patterns in the space below.

This is the answer for the question #1



Well, I can't actually explain you this right now. There isn't enough information. Let's go to the question #2.


2. Make a table to show the results of your investigation.



This is question 2. The answer is right below. =)



Here are my explanation:

The pattern is that the x row is starting at 1, getting larger by 1, and also in the numerical order. You could also see that the y row starts at 6, getting larger by 3 and the multiples of 3. This could be the answer for the question 3, which says to describe the patterns found in each row.

3. Describe the patterns found in each row.

x row
- starts at 1
- increases by 1
- numerical order

y row
- starts at 6
- increases by 3
- multiples of 3

Now, it's time to explain question 3B.

3B. Describe why the patterns increase the way that they do.

- The pattern increases by 3 because you are adding 3 legos to the edge to create the next figure.

My explanation is exactly the same as my answer for the question 3B.

4. Describe the relationship between the two columns.

- y is larger
- you have to add (+) or multiply (x)
- three times (figure #) plus 3
- 3n + 3


Here is my T chart.



4C. Write an algebraic equation to show this relation ship.

n = figure #
3n + 3

5. Predict what the 20th, 35th, and 99th diagram will look like.
(DO NOT PANIC)

20th -
n= FIGURE NUMBER
3n + 3 =
3(20) + 3 =
60 + 3 = 63
63 = 63

35th -
n= FIGURE NUMBER
3n + 3 =
3(35) + 3 =
105 + 3 = 108
108 = 108

99th -
n= FIGURE NUMBER
3n + 3 =
3(99) + 3 =
297 + 3 = 300
300 = 300

6. Predict which diagram will use 30, 50 and 125 blocks.
(Well, you have to change 50 into 51, change 125 into 126)

30 legos -
n= FIGURE NUMBER
3n + 3 =
3(9) + 3 =
27 + 3 = 30
30 = 30

51 legos -
n= FIGURE NUMBER
3n + 3 =
3(16) + 3 =
48 + 3 = 51
51 = 51

126 legos -
n= FIGURE NUMBER
3n + 3 =
3(41) + 3 =
123 + 3 = 126
126 + 126

For this question, as the questions says, you have to predict. Sometimes it takes long time to predict. There is short cut. Mr. Harbeck will teach us someday.^^
For example, let's figure out 30 legos.

n = figure number

3n + 3 = 30
......- 3.....- 3
3n = 27
..............27/3 = 9
3(9) = 27
27 = 27

This is a correct way to solve this kind of problems.

FINALLY THE LAST QUESTION! =)

7. Make a graph for the first 6 terms and label the line according by it's equation.

You have to make a graph for this question.



HOME WORK:

Today's homework is to finish up 2 blue sheets.
One is called Pyramid power and the other one is called Build me a house #2

This is just to show the pictures together.

I'm finally done and I hope you actually understand it.

Please comment if you want me to change something. Thanks. =)

Scriber Diving - Patterns and Relations 1

1. Draw out the next two patterns in the space below.



This album is powered by BubbleShare - Add to my blog






2. Make a table to show the results of your investigation.



3. Describe the patterns found in each row.
x = Gets larger by 1
= Numerical order
= Consecutive numbers
= Starts with one

y = Gets larger by 2
= All odd numbers
= Starts with 2

3.B. Describe why the patterns increase the way that they do.
-The pattern starts at 3 because it takes three tooth picks to create a triangle.
-It then goes up by 2 because there is already 1 triangle and you're just sharing a tooth pick.
-They are all odd numbers because...

4. Describe the relationship between the two columns.
= y is larger
= We have to + or x
= figure + figure + 1
= 2 times figure + 1
= 2n + 1
= n = figure #

4.C. Write an algebraic equation to show this relationship.
= n = figure #

2n + 1 =
2(30) + 1 =
60 + 1 =
61

5. Predict the 20th, 35th, and 99th diagram will look like.

n = figure #

20th -
2n + 1 =
2(20) + 1 =
40 + 1 =
41




35th -
2n + 1 =
2(25) + 1 =
50 + 1 =
51




99th -
2n + 1 =
2(99) + 1 =
198 + 1 =
199



6. Predict which diagram will use 31, 51, and 125 tooth picks.
2n + 1 = tooth picks

31 tooth picks -
2n + 1 = 31
2(15) + 1 = 31
30 + 1 = 31
31


51 tooth picks -
2n + 1 = 51
2(25) + 1 = 51
50 + 1 = 51
51



125 tooth picks -
2n + 1 = 125
2(62) + 1 = 125
124 + 1 = 125
125
