HCF = 12 (since 36 = 24×1 + 12 and 24 = 12×2 + 0)
Q2. Find the value of (sin 30° + cos 60°).
sin 30° = 1/2, cos 60° = 1/2 → Total = 1
Q3. Solve: 2x² – 7x + 3 = 0.
x = 3 or x = 1/2
Q4. Find the area of a triangle with base 10 cm and height 8 cm.
Area = 1/2 × 10 × 8 = 40 cm²
Q5. What is the value of sin²A + cos²A?
sin²A + cos²A = 1 (identity)
Q6. Find the mode of: 3, 5, 5, 6, 6, 6, 7.
Mode = 6 (highest frequency)
Q7. Find distance between (2,3) and (6,9).
Distance = √[(6-2)² + (9-3)²] = √(16 + 36) = √52 = 2√13
