Week 3 in Math 10

Finding the height of a triangle using angles and one measurement.

Step 1: Draw and label your triangle.

Step 2: Label the sides of the right triangle; the Hypotenuse is always the longest line and it is across from the 90 degree angle, (box in the bottom left of triangle).

Step 3: Label; the Adjacent is the side that is closest to the angle that you are using.

Step 4: Label; the Opposite is the side that is across from the angle being used.

Step 5: Select either Sine, Cosine, or Tangent;  choose either Sine, Cosine, or Tangent by using the acronym Soh, Cah, Toa. This acronym shows that you would divide you given angle by sine if you have information on either the Opposite side or the Hypotenuse side and you need to solve either the Opposite side or the Hypotenuse side, you would use Cosine if you have information on either the Adjacent side or the Hypotenuse side and you need to solve either he Adjacent side or the Hypotenuse side, if you have information on either the Opposite side or the Adjacent side and you need to solve either the Opposite side or the Adjacent side. In this case you have information on the Hypotenuse side and you need to solve the adjacent side so you would use Cosine.

Step 6: Write out the equation.

Step 7: Isolate X; in this case you would move the 25 that divides X to the other side of the equation. The 25 would multiply Cos63 because 25 multiplying is the inverse of 25 dividing.

Step 8: Enter you equation into your calculator, then round that number to the nearest tenth.

Week One in Math 10

One of the most important math concepts that was taught in week one math was finding the lowest common multiple (LCM) of two or more numbers, using prime factorization. I, Stefano Moino, used four steps to come to the product of any LCM. Step 1, Write out your two or more number and create a factor tree for each of them; a factor tree is when you branch off of number to find the factors that make up the number, until you reach its prime factors, (as seen in examples below). Step 2, write out the prime factors that you have come up with, for both or multiple numbers, and circle the common factors. Note: you must circle your common factors at a 1:1, 2:2, 3:3  ratio, and the commons factors can only be circled from top to bottom or diagonally not across the same row, (as seen in examples below). Step 3, put your common numbers on a ratio of 1:2 into one bracket and all of your uncommon number into a different bracket and multiply all your prime factors together in each separate bracket, then multiply each bracket together, (as seen in examples below). Step four, after you find the product of your two bracket you have found the final answer, (as in the examples below). This first example is finding the LCM of 9 and 12.

The second example is finding the LCM of 375 and 756.
