6 × sin(30°) × cos(30°) ÷ cos(30°) - sin(30°)= 6 × (1/2) × (√3/2) ÷ (√3/2) - (1/2)= 6 × (1/2) × (√3/2) ÷ (√3/2) - (1/2)= 6 ÷ 2 - 1/2= 3 - 1/2= 2.5
Therefore, the final answer is 2.5.
6 × sin(30°) × cos(30°) ÷ cos(30°) - sin(30°)
= 6 × (1/2) × (√3/2) ÷ (√3/2) - (1/2)
= 6 × (1/2) × (√3/2) ÷ (√3/2) - (1/2)
= 6 ÷ 2 - 1/2
= 3 - 1/2
= 2.5
Therefore, the final answer is 2.5.
