Week 8 was continuing on from last week when we began Trigonometry, this week was just an addition to the lessons. We looked into how to find missing angles using Trig. It took me longer to figure out than any other thing for this unit.
In both shade of blue you have the BASICS. A right triangle, a missing angle, the measurements 30 m and 12 m. In red I wrote ‘What I Know’. I can easily find all the sides if I have an angle and a right angle. I labeled each side along with L M S witch tells me normally the hypotenuse is the L / Large as it is the longest side, and where ever the reference angle is, directly across from it is the M / Medium side that is exactly the same rule for finding the opposite side. That leaves the adjacent side leftover to mark S / Small. In black there is the equation to solve for the missing angle, in this case you only have the numbers 30 and 12 and once you have labeled their sides you use SOH CAH TOA and solve. In this case I used sine as i had labeled and found out that the hypotenuse is 30 m and 12 is the opposite side. Once I plugged them into the equation for sine, I found that I didn’t have the angle so using algebra knowledge you have to get theta by its self. In order to do that you have to use INVERSE SINE. You can do this for all, cosine or tangent. and just right it with a negative one as I did in the photo. Hint: There should be a button on your calculator! I got the result 24 out of all of that! In green I added a hint, that symbol thats in the spot where the angle should be is a greek letter called THETA. It is used a lot in math especially in angles.
In Math 10 this week we started Trigonometry. It is pretty straight forward one you have labeled correctly. I will be demonstrating finding a missing side length using Sine, Cosine, or Tangent. Keeping SOHCAHTOA in mind. I have created a video that will show step by step how to solve for a missing side length.
In the short story “The Watch” by Elie Wiesel, he wrote this journey to take us through his upsetting, yet motivationalodyssey as a survivor of a Nazi camp during WWII. Elie was born and lived in Sighet, Romania, he was raised following the Jewish religious beliefs in a ghetto area. Forced to live in this area, Elie and his family still manage to live the best life they can. Being Jewish he had a bar mitzvah at the age of 13, he received a gold watch: “As for me, my only possession was my watch. (Page 1)” This was a general gift to show the newly made man that he now had responsibilities and had to act more carefully towards the Torah, its rules and laws. Taken to the Nazi camp at 15 he found himself, along with his parents and sister, burying his watch along with all their most valuable or attached items before they left. They buried them in their garden. During the time spent in the Nazi camp Elie, his family and others trapped in this horrible place had the mindset that they would get out and retrieve their past lives. Twenty years later Elie went back to the exact spot in his old garden that he buried the watch and started to dig. Once he found it he reburied it. This symbolized him moving on from his dreaded memories and leaving them buried with his watch: “In retrospect, I tell myself that probably I simply wanted to leave my past behind me, underneath the silent soil, a reflection of my presence. (Page 5)” According to this short story Elie Wiesel recovered from extreme hardship by burring his watch along with horrible memories.
I did awesome on my quotes.
I could work on my image choices and writing sentences that need to be there. Not ‘just beach’ sentences.
Getting heavier into measurement we received a formula sheet, one that we can use on tests and in the homework so we do not have to memorize all of them. This was very helpful and much appreciated. Unfortunately we had to remember one or two things; finding the slant hight of something with a triangular shape or comes to a point and the formulas for hemi-spheres.
I am going to demonstrate finding the slant height of something with a triangular shape or a shape that comes to a point. There are different shapes you might need find the slant hight for, like a pyramid or a cone.
First lets see the shape we will be using… A cone!
A cone is a shape that looks like a flipped ice cream cone.
Next you will be given some measurements, before this you should know the names of measurements that you need to know.
Blue- the true height
Red- slant height
(the radius is half of the diameter)
Now lets say, you have been giving some measurements…
So, you have been given the True Height and the Diameter, but need to find the slant height…
You have to follow a formula that calls for the radius to be involved, we already know that the radius is half of the diameter therefore..
Our radius is 6.
To find the slant height you need to follow a formula…
h = true height
r = radius
s= slant height
Now you simply plug in the numbers you know into the formula.
Solve what you can… And get your answer!
The Slant Height is equal to 10. The slant height is 10cm.
This week in Math 10 we started our Measurement Unit. I learned that estimating can now become a bit more accurate just by using our body to measure things. It also helps if you know the measurements of the body parts you are using to estimate the real size.
Large Objects – Face of your Fridge:
You could use the width of your body (shoulder to shoulder) and measure the face that way.
Medium/ Regular Objects – Computer Face:
You could use the width of your hand (edge of pinkie to edge of thumb) and measure the face that way.
Small/ Tiny Objects – Plastic Water Bottle Cap:
You could use the height of coins stacked (dimes are good) and measure the height that way.
To experience a great breakfast is to feel energized after a great meal.
Is breakfast an essential in everyones daily routine? What is your favourite part? The eggs? The bacon? Toast?
Is it your local neighbourhood greasy spoon? Or your go to with Grandma?
Denny’s, the one stop breakfast joint that everyone enjoys. Greeted at the door, I find myself falling in love with the surrounding environment. The smile I receive is given by the host. It was warming. The over whelming aroma of freshly brewed coffee that when is stirred looks like a black whirlpool and of course the bacon that is undeniably the most distinctive, welcoming scent of all. Tight booths, glossed wooden tables, green napkins embracing the cutlery with a snug, warm hug, a horizontal bar where the kitchen staff is, thin green carpet covering the floor like fresh snow on the tip of a mountain. Once seated, looking at the menu, it’s a tough decision of what to eat. Normally, going for the Classic Eggs Benedict; an easy buy, or Moons Over my Hammy; a simple, and reasonable price, I want a fulfilling meal that can fuel me before a soccer match or create a warm temperature through my whole body after play in the icy, cold rain. I go for the scrumptious sandwich,
Moons Over my Hammy. Laughing, orders being taken by involved employee’s, newspapers flipping, and of course the MMMMM that comes out of my dad at the end of the table where he sinks his teeth into fluffy, yet cooked to perfection pancakes. All sound waves are traveling amongst each other like the employees delivering meals. Warmth, with eggs that are fluffy, ham that is smokey, swiss cheese and cheddar cheese that’s melted to perfection all in my mouth at once. Denny is not just the name of your favourite relative but your favourite breakfast spot too.
