Study Notes
Basic Mathematical Concepts
- The square root of 144 is 12, as (12 \times 12 = 144).
Triangle Angle Calculation
- In a triangle, the sum of all angles is always 180°.
- If two angles are 45° and 60°, the third angle can be calculated as (180° - (45° + 60°) = 75°).
Solving Linear Equations
-
For the equation (3x - 7 = 8):
- Add 7 to both sides: (3x = 15).
- Divide by 3: (x = 5).
-
For the equation (3x - 7 = 11):
- Add 7 to both sides: (3x = 18).
- Divide by 3: (x = 6).
Rectangle Perimeter Calculation
- The perimeter (P) of a rectangle is calculated using the formula (P = 2 \times (length + width)).
- For a rectangle with a length of 8 cm and a width of 5 cm, the perimeter is (P = 2 \times (8 cm + 5 cm) = 26 cm).
