the length of YZ that is rounded to 3 significant figures using XY = 3.2cm. XZ = 1.7cm is 1.50 cm
Explanation :
Given : XY = 3.2cm. XZ = 1.7cm.
We need to calculate the length of YZ
From the given information we can see that Z lies between X and Y
So we add XZ and ZY to get XY
![XZ+ZY=XY](https://tex.z-dn.net/?f=XZ%2BZY%3DXY)
Substitute the given values and solve for YZ
![XZ+ZY=XY\\1.7+ZY=3.2\\Subtract \; 1.7\\ZY=3.2-1.7\\ZY=1.5](https://tex.z-dn.net/?f=XZ%2BZY%3DXY%5C%5C1.7%2BZY%3D3.2%5C%5CSubtract%20%5C%3B%201.7%5C%5CZY%3D3.2-1.7%5C%5CZY%3D1.5)
Round the answer to 3 significant figures.
After rounding to 3 significant figures , the length of YZ=1.50 cm

Perimeter Formula [Triangle]: P = L₁ + L₂ + L₃
- L₁ is one side
- L₂ is another side
- L₃ is the 3rd side
Step-by-step explanation:
<u>Step 1: Define</u>
L₁ = (6a - 3b)(6a - 3b)
L₂ = (5a + 5c)(5a + 5c)
L₃ = (8c - b)(8c - b)
<u>Step 2: Find Perimeter</u>
- Substitute in variables [Perimeter - Triangle]: P = (6a - 3b)² + (5a + 5c)² + (8c - b)²
- Expand [FOIL]: P = (36a² - 36ab + 9b²) + (25a² + 50ac + 25c²) + (b² - 16bc + 64c²)
- Combine like terms (a²): P = 61a² - 36ab + 9b² + 50ac + 25c² + b² - 16bc + 64c²
- Combine like terms (b²): P = 61a² + 10b² - 36ab + 50ac + 25c² - 16bc + 64c²
- Combine like terms (c²): P = 61a² + 10b² + 89c² - 36ab + 50ac - 16bc
- Rearrange variables: P = 61a² - 36ab + 50ac + 10b² + 89c² - 16bc
- Factor: P = a(61a - 36b + 50c) + 10b² + 89c² - 16bc
